Italian
From acclaimed chef, author and restaurateur Scott Conant comes a quintessential Italian eatery for local gourmands and travelers alike, Masso Osteria. Located at Red Rock Casino, Resort and Spa and inspired by the rocky desert landscape that surrounds Summerlin – “Masso” is Italian for “boulder” – the restaurant captures the convivial spirit of a classic osteria, offering refined, craveable Italian fare in a lively setting. A fitting destination for both special occasions and casual weeknights with friends, Masso is a return to form for chef Conant, whose menu of house made pastas, antipasti and savory wood-fired sides reflects his guiding philosophy: to create unforgettable dining experiences rooted in soulful cooking and generous hospitality.

The menu was extremely limited. We tried this place to try to get off of the strip, and I wish I would have stayed on the strip and paid more. While the prices were slightly lower, but the portions were much smaller.

Excellent food, great quality, unique tastes.

Didn’t like the set up of tables. They were way too close together. And I’m fairly petite and I was very uncomfortable!

Masso is always our favorite and Trip is one of the best servers you can find. The food is delish and we always try new combos of something. Sometimes its just appetizers and wine, sometimes just entrees. The pork and veal parm are to die for. The Lamb is always mouth watering. You won't be disappointed.

I was disappointed with the meal overall. I guess I expected a more flavor meal. We had soup, and 2 appetizers. The garlic bread was ok. I had a pasta dish and my husband had the branzino. Again my pasta was just ok. The branzino was delicious!!

Masso has become our "go-to" place for special occasions. We thoroughly have enjoyed each of our visits. The food is excellent...challenging, but not in a "food-snob" sense. Top-notch, wonderfully prepared meals are the hallmark. Wine selection includes half bottles as well as by-the-glass...and superior wines throughout. Staff is very well-prepared to answer questions. They are also "there" but not "THERE!"

Masso Osteria breaks from the rut most Italian American restaurants fall into where they serve the same combo of pasta, sauce, cheese, meat. The menu is authentic Italy meets American creativity. My wife and I love this place. The staff is knowledgable and fun.

Have been here a few times and did not like the waiter this time. Food was still great but the weather felt the need to explain the appetizers. No need to tell people that this is a salad, this is a Stromboli Too obvious and the waiter was so pompous about it.

This was our second time here in less than two weeks! Cristian, the general manager, is amazing and the service and food are excellent. We were lucky enough to be there on an evening that Scott Conant was there, and he graciously spent time with us as well as many of the patrons of the restaurant. This restaurant is now a favorite and a “go to”. Blessed to have it in close proximity to home!!!

Service was awesome! Recognized our reservation quickly and sat us at a great table. Love the decor! And the waiter was awesome, didnt oversell us and I appreciated that he asked what we were interested in before rattling off specials that we may not care about. He also asked us if we were interested in the football game playing and would give us score updates. I felt like he genuinely cared about our experience not just about getting food for us. The cheesy bread is a must! And the branzino is cooked perfectly! The leg of lamb is just stupid good! Love love love

I brought my Mom here last Saturday because I had two amazing meals here in the past two weeks. However as delicious was the pasta on these past two occasions, was the pizza disappointing on this special night with Mom. It was as if Masso was conserving the mozzarella cheese delegating only half the slices. We actually had only four slices with the cheese. CRAZY! The Heirloom tomato burratta and beet salads were wonderful but being cheap with the ingredients on the pizza was a real turn off.
