Fiamma has a create your own 4-course menu which I felt was a really good deal. $60 bucks (add $35 for wine pairings).
Went w/ the boyfriend for his birthday and we both did the 4 course menu
1st course - Kobe beef risotto balls w/ marinara sauce and cheese. We also got the buffata mozzarella that came with these really great sweet red bell peppers and prosciutto. both were excellent. The risotto balls were crisp on the outside, inside was perfect as well. the mozzarella was fresh and melted in my mouth.
2nd course - after reading all the yelp reviews, we both got the lobster gnocchi. it definitely lives up to the hype and surpasses it. The sauce is amazing and not overpowering, they gave huge pieces of lobster meat and the gnochhi was perfectly cooked.
3rd course - fillet of beef and the braised short rib. By this time the boyfriend and I were starting to feel like we were going through food coma. the short rib was succulent and melded well with the mashed potatoes. the flirt had a great sauce on top and was cooked perfectly.
4th course - the dessert was the standard one that's given (no choice). It was a pana cotta with figs and a balsamic honey as well as a chocolate dome thing that had ice cream in it and chocolate and hazelnuts with it. The pana cotta was a slight disappointment, but the balsamic honey sauce was really great. The chocolate dessert was great though, however I felt that it didn't compare to the other 3 courses.
Service was excellent. They were so attentive, and asked up front whether we needed to be somewhere soon. Since we weren't seeing a show, we definitely took our time and they paced out the dinner perfectly, including the 10 minute "breather" my boyfriend and I needed between the main course and dessert.
All in all, if I had the money, I would go to Fiamma every time I'm in Vegas...until then I'll save it for special occasions.
