This used to be Corsa Cucina but they changed the name and changed the menu (although the web link still has "Corsa Cucina" in it even though the main Wynn website says "Stratta").
There are some things similar to Corsa Cucina, namely the pizzas. I had the pizza with shitake mushrooms, mozzarella, goat cheese and truffle oil. I have to say, it was excellent. I also had a side of rapini, which was also excellent - lots of garlic. I also tried the fried cheese bites that my friend ordered and they were tasty - little triangles of cheese between bread with two different sauces. They were not amazingly memorable but they were good in a comfort food sort of way. The bread they served us came with a pesto sauce to dip and the pesto was excellent.
They have a smallish but decent wine by the glass list and the service at the bar is excellent. We chose to sit at the bar so we could have a faster dinner and get back to gambling and it was very pleasant. The bartenders were friendly and we got our food and drinks very quickly. The rest of the menu looked pretty good, too - lots of pastas and also meats and fish, several different pizzas, interesting sides. It's pricey for both food and wine but it's a nice place for a somewhat more casual dining experience at the Wynn. You do feel like you are sitting in the casino with the view from both sides and I think they sort of were going for that; it definitely makes it more casual than the other restaurants at the Wynn. I would like to return here for a full dinner and I would absolutely return to have a glass of wine and pizza or apps at the bar.
