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.

Brunch here was wonderful! We highly recommend the live stations. The Sunday morning dj was awesome, and the bar had the football games on. We will definitely return!

Something missing as compared to Scott's NYC restaurants (Scarpetta, L'Impero, Barolo); Food was very good but just a touch off; Crowd was a weird mix; Probably not worth the drive from the Strip to get to Red Rock Casino.

A nice addition to the Red Rock restaurant scene. Modern twists to Italian classics. Excellent pomodoro sauce, Gemeli, lamb shank is outstanding. If you like espresso coffee then you MUST try a buona notte drink. One of the best mixtures in Vegas. Prices are fair and not too expensive. Cent'anni!!

Excellent food, service, and wine. Only slight is there was a large party (25+) ending their event during the first 30 minutes of our arriving making it very loud. Had I known I would have made a later reservation. But if that is my only complaint, in the grand scheme of things it is a petty one.

Went to Masso for dinner. The food was delicious (the gnudi pasta dish, beet salad and budino dessert), the service was great (attentive, helpful but not intrusive, the atmosphere romantic and comfortable. I will return to dinner again and try brunch. A great addition for Red Rock.

One of my guest was burnt by an appetizer that was served on a iron skillet. The handle had no protection on. Took a little bit to the attention of staff to get some ice. They were quick to have the security come and have an accident report filled out. We asked for some first aid cream to put on the burn and they told us we had to an urgent care for that. No one ever came back to the table to ask how my guest was doing.

Tonight was my first time visiting Masso Osteria and the food was nothing short of AMAZING! My family and I had the woodfire grilled octopus and recco style garlic bread to start. For our main courses, we shared the lamb shank, veal milanese with the chef’s pomodoro sauce (recommended by our server), and squid ink tagliolini. Everything arrived in a timely manner and was delicious!

The service was wonderful as well! Our server, sommelier, and wait staff were all very friendly and attentive. Overall I enjoyed my experience and will definitely be returning in the future!

We had a reservation at 7:00 for 4. Once seated, we waited 25 minutes to get water. Then our waiter disappeared and we had to flag down the manager for a cocktail order. Then the fire alarm goes off and we waited again to order our appetizers. That should have been a sign for us to leave!!! We ordered 4 appetizers followed by 4 entrees. All of which were just average. The service was below average and after spending $400 before tip, I won’t be back. There are too many restaurants in this town that serve more delicious food with better service so follow my lead and skip this restaurant!!

I hosted a small Friendsgiving get-together with the girls for happy hour and Masso never disappoints! This was my first time with a pretty sizeable group (8 of us) and the service was stellar, they happily accommodated us in the bar area, and the food was fantastic, as always! Definitely coming back and absolutely recommend!!

A couple suggestions:

2) Offer pepper with the salads. We had to ask.

I have eaten here a couple of times and enjoyed each visit! I went to enjoy the special event with Chef/Owner Scott Conant and Chef Aaron Sanchez. They both offered a delicious tasting of special dishes and it was worth the price! Each dish was paired with a delicious wine that worked perfectly with the meal! I plan to go back with my table mates (sat with 5 other people I met that night) to try the brunch! I plan to go there again real soon.

Chef Scott Conant was absolutely wonderful and he completely made our experience! The food was outstanding and I can’t wait to go back and try other dishes. Having Chef Aaron Sanchez there was a bonus and I loved how they played off one another. It was very surreal watching Chef Scott Cooking our meal and Chef Aaron expediting. Excellent hospitality and a memory and experience I won’t forget!

Excellen t menu. From cold and hot appetizers, my favorite is the creamy polenta with truffles. Good salad and soup selection. Excellent pasta dishes. Very nice entree. Try the branzino, like fish? You'll love this prep on brandzino. Great service as well. Try the buona notte cocktail to end meal. A one of a kind treat!!

We ordered from the menu for the Sunday brunch. Our eggs came out cold. Our server nicely reordered but this time they were undercooked and runny. The hollandaise sauce was cold and flavorless. We ordered a side of fingerling potatoes which were good but came out after all the other food ( even the reordered)

We didn’t not have the buffet but it seemed ho him for the price


Sunday brunch is not ready for prime time
