Beso is located in Crystals shopping mall next to Aria. First of all, good service. We were seated promptly and immediately given the wine list and everything came out very quickly. Surprisingly quick. Beso ranges in the upper $20s to $50s for entrees so with tip and tax you'll be paying about $75 a person if you want drinks and sides.
We ordered the oyster shooters (they're not alcoholic) and there were very good. I preferred the tomato gazpacho oyster shooter.
For entrees we had both the tuna and the salmon. Both were wonderfully prepared and the portions were not small. You have to order sides separately, but they are very large sharing portions. The wild mushrooms side was $11 and way too large for two people to consume.
Somehow we had room for dessert after seeing the dessert menu. The churros were simply amazing with a caramel sauce and creme. I still don't know how we managed to eat all six of them.
The bathroom is upstairs are requires taking an elevator and walking through the night club. There's an outside patio seating area as well as a dining room. The dining room is not too large and the booths are comfortable. Our table had a nice view of the Aria's fountain and even New York, New York's fake Empire State Building, so if I squinted just right I felt like I was back home eating at the W's Zylo Steakhouse.
