Excellent addition to the Cosmopolitan. Probably doesn't hurt that it generates more revenue than the art gallery it replaced.
I feel this place has more of a focus on the food than some of the other restaurants in this hotel. Some, without naming names, are more about the scene than the food. Luckily for us, Zuma comes through with excellent food.
The skirt steak came with a cool chimichurri sauce that was pretty good. Every dish comes with salt (himalayan?) on the side. Use very carefully, and don't use a lot, doesn't need that much. The robata skewers crushed it, the chicken wings and the beef with shishito pepper were pretty big and full of flavor. Get sushi if you want but I'd focus on their other dishes, like from the robata, skewers, or the bigger plates.
Handcrafted ice and cocktails sitting in barrels are a few of the more inspired drinks on the menu. I overheard a convo the bartender had about sour beers and my ears perked up. He gave me the beer even though they don't sell it and only use it in cocktails. What a nice gesture!
Do not come here expecting just sushi. It's an izakaya! Sushi is there, but it's not the main event. Enjoy the robata grill and the shared plates.
