Tapas in Vegas!
I'm in the minority but I cannot stand Firefly. I think their food is bland and unimaginative.
For tapas I love Cafe Ba Ba Reeba. I know it's a Lettuce Entertain You restaurant but I think they do a good job for a good price. Plus their sangria is fantastic. You really can't go wrong on a summer afternoon, sitting outside, enjoying the tapas and sangria.
