Jaleo is a modern tapas style restaurant located in the Cosmopolitan. Hip, sparse lighting, and a menu that i couldn't stop ordering from. It wasn't only because the food sounded so amazing but also because the portions were certainly small. It is tapas after all. Even so, anticipate spending a few $ and ordering a lot of plates to feed a large group.
Make sure you order a pitcher of Sangria! Best sangria i've had in a while. It's infused with watermelon, orange, basil, and other refreshing fruits.
My recommendations include:
Lobster Paella
Scallops
Garlic Shrimp
