Hawthorn Grill Las Vegas: Steakhouse Dining at JW Marriott Summerlin

Some restaurants make more sense once you look at everything around them, and Hawthorn Grill is a good example.

Located inside the Spa Tower at JW Marriott Las Vegas Resort & Spa, part of The Resort at Summerlin, Hawthorn Grill gives locals a traditional steakhouse experience without heading anywhere near the Strip. The restaurant combines steaks, seafood, American classics, cocktails, wine, and one of the more relaxing outdoor dining settings we’ve found on this side of town.

We first experienced Hawthorn Grill during a staycation at the resort and returned again on May 9, 2026. The return visit gave us another chance to appreciate how much the dining scene around the property has grown. Hawthorn remains the place to go when you want the full sit-down steakhouse experience, but there are now enough restaurants around the resort to make this corner of Summerlin worth exploring on its own.

Hawthorn Grill at The Resort at Summerlin

Hawthorn Grill sits inside the Spa Tower at JW Marriott, away from much of the casino activity. That separation gives it a quieter atmosphere than you might expect from a resort restaurant.

The dining room feels polished but comfortable, with enough formality for a date night, anniversary, business dinner, or celebration without turning the evening into an overly formal experience. Hawthorn Grill officially describes its dress code as business casual.

The restaurant also has a lounge and a spacious outdoor patio surrounded by foliage with the sound of nearby waterfalls. Fire pits and heaters make the patio more usable when temperatures cool down, and it gives Hawthorn Grill a personality that feels different from a typical enclosed steakhouse.

One detail we remembered from our original visit happened before the meal even started. As we were walking toward our table, we watched one of the chefs step outside to gather fresh herbs. It was a small moment, but seeing ingredients being picked just steps from the dining room made the restaurant feel a little more personal.

What We Tried at Hawthorn Grill

Our experiences at Hawthorn Grill have centered on the steakhouse side of the restaurant. The menu continues to evolve, so individual dishes and preparations can change, but these were some of the plates that stood out during our visits.

House Bread

Dinner started simply with warm house bread and creamy butter.

Good bread can disappear surprisingly quickly at a steakhouse, and this was one of those baskets. It was soft, warm, and exactly what we wanted while settling into the meal.

Lobster Bisque

The Lobster Bisque immediately stood out because it wasn’t as thick as many steakhouse versions we’d tried before.

That lighter texture initially caught me off guard, but the flavor quickly changed my mind. It was rich without becoming overly heavy and worked especially well as the beginning of a larger dinner.

Steakhouse Sides Made for Sharing

For us, a steakhouse meal is rarely just about the steak. The sides are part of the experience, especially when everyone at the table can share a few different dishes.

Cremini Mushrooms

The Cremini Mushrooms were prepared with garlic, thyme, parsley, and white wine during our visit.

They had the deep, earthy flavor you want next to a steak, with enough herbs and wine to keep them from feeling too heavy.

Crispy Brussels Sprouts

The Crispy Brussels Sprouts went in a completely different direction.

Ours arrived crisp with aioli, giving the table a combination of crunch, richness, and a little heat. They were easy to keep reaching for between bites of everything else.

Our Main Courses

Caesar Salad

My wife went with the Caesar Salad, which during our original dinner was much more substantial than the simple side salad the name might suggest.

It came with baby heart romaine, sourdough croutons, white anchovies, tomato, shaved Parmesan, and prosciutto. The prosciutto added enough richness to make the salad work as a full entrée rather than something that felt like an appetizer.

16 oz. Ribeye

The Steak That Defined Our Dinner

I went with the 16 oz. Ribeye, which is usually the cut I gravitate toward when trying a steakhouse.

A ribeye can be unforgiving. When the marbling isn’t handled properly, all of that fat that should make the steak flavorful can instead become chewy or unpleasant.

Our steak landed on the right side of that equation. It was juicy, tender, full of flavor, and cooked well enough that the marbling added richness rather than getting in the way.

It became the dish I remembered most from the dinner.

Service and the Waterfall Patio

The setting is a major part of why Hawthorn Grill works.

Service during our visits has felt attentive without constantly interrupting the meal. That matters at a restaurant where dinner is supposed to take some time.

The outdoor space may be the restaurant’s biggest advantage. The patio overlooks lush landscaping and nearby waterfalls, giving you a completely different atmosphere from the dining room. Hawthorn Grill also uses fire pits and heaters outdoors, which helps extend patio season beyond just the warmest months.

More Restaurants Inside The Resort at Summerlin

One thing that has changed since our first Hawthorn Grill experience is just how many restaurants we’ve now covered around the same property.

That makes The Resort at Summerlin more interesting as a dining destination rather than simply a place with one or two restaurants attached to a casino.

If Italian food sounds better than steak, ai Pazzi is another full-service dinner option inside the resort. We actually ate there during the same staycation that introduced us to Hawthorn Grill, giving us two completely different dinner experiences without leaving the property.

For Asian cuisine, Jade Asian Kitchen & Noodles shifts the experience toward Chinese dishes, sushi, noodles, and teppanyaki. Its setting also includes outdoor seating near the resort’s waterfall landscaping.

The resort’s newer additions have expanded the choices even further. Nom Wah brings the historic New York dim sum brand to Summerlin in a much more casual format, while Tacos 1986 serves Tijuana-style tacos from the resort’s food hall. Both are good examples of how you can eat somewhere completely different at the same property without committing to another formal dinner.

Then there’s Wineaux, which works particularly well when you want the evening to center more around wine and conversation. Its combination of wine shop, bar, and lounge gives The Resort at Summerlin another date-night option that feels very different from Hawthorn Grill.

Breakfast and Happy Hour at Hawthorn Grill

Hawthorn Grill isn’t limited to dinner.

The restaurant currently serves breakfast daily from 7 AM to 11 AM. That makes it useful not only for hotel guests but also for locals meeting for breakfast or looking for a quieter morning option around Summerlin.

Happy Hour runs daily from 4 PM to 6 PM at the bar and patio. It’s a much more casual way to experience the restaurant if you aren’t planning a full steakhouse dinner.

More Dining Around This Part of Summerlin

If you want to explore beyond the resort without going far, Tivoli Village and Boca Park add even more options along Rampart Boulevard.

At Tivoli Village, Echo & Rig gives steak lovers a completely different experience. Its combination of modern steakhouse and working butcher shop makes it a natural comparison for anyone exploring steakhouses around Summerlin.

For Italian food, Al Solito Posto offers handmade pasta, Neapolitan-style pizza, seafood, cocktails, and an upscale dining room at Tivoli Village.

Continue a little farther along Rampart Boulevard and Boca Park opens up another group of restaurants. One we’ve spent time at is Hussong’s Mexican Cantina, a much more energetic option built around Mexican food, tacos, margaritas, and a lively bar atmosphere.

Together, those areas make this stretch of Summerlin particularly useful when planning a night out. You can choose the atmosphere first—steakhouse, Italian, Mexican, dim sum, tacos, Asian food, or a wine bar—without traveling very far.

Planning a Visit to Hawthorn Grill

Hawthorn Grill is located at 221 North Rampart Boulevard inside the Spa Tower at JW Marriott Las Vegas Resort & Spa.

The restaurant currently serves breakfast from 7 AM to 11 AM daily. Happy Hour is available from 4 PM to 6 PM daily. Dinner runs from 4 PM to 9 PM Sunday through Thursday and 4 PM to 10 PM Friday and Saturday.

Complimentary valet parking is available at the Spa Tower, which is the easiest entrance to use when Hawthorn Grill is your main destination.

The restaurant lists its dress code as business casual and accepts reservations. Hawthorn Grill also has more than 3,200 square feet of dedicated event space, including private and semi-private areas for celebrations, business dinners, receptions, and other group events.

Why Hawthorn Grill Still Works for Us

Returning to Hawthorn Grill on May 9, 2026 reinforced what stood out the first time.

This isn’t only about ordering a steak. The combination of the dining room, lounge, waterfall patio, wine and cocktail program, attentive service, and the ability to spend an entire evening around The Resort at Summerlin gives Hawthorn Grill more context than a standalone steakhouse.

The resort itself has also become a much stronger dining destination. On different visits, we can now choose between Hawthorn Grill, ai Pazzi, Jade, Nom Wah, Tacos 1986, or Wineaux depending on what kind of night we’re looking for.

For Hawthorn Grill specifically, we still think it works best when you want to slow the evening down: make a reservation, order a few sides for the table, enjoy a steak or seafood entrée, and let dinner be the main event.

For locals looking for a steakhouse in Summerlin, that’s exactly where Hawthorn Grill fits.
