Julian Serrano's tapas restaurant will not disappoint you. It can sometimes be difficult to find vegetarian options at a tapas restaurant but even though they have a relatively small menu there was still plenty for me to choose from. I absolutely loved the manchego cheese sandwich, mushroom risotto, gazpacho (no lobster), and their yummy chocolate dessert options. It's a small restaurant (in the lobby of Aria hotel), so be sure to make a reservation beforehand. I'd definitely return for some quick bites when in Vegas.
