If you are looking for something really good in the Summerlin area then you have to make a trip to Mastrioni's. I've yet to have a bad meal there! Start with the Mastrioni's salad and you can't go wrong! Ask them to split it when you order, it's enough for two people. An amazing salad with Gorgonzola, walnuts, pears, cranberries and vinaigrette dressing. Mussels with red sauce are excellent and I highly recommend the seafood linguine combo. The special on one visit was linguine with clams, mussels and shrimp in a red sauce. Excellent! The shrimp are huge and fresh! Service is attentive.
