This is not clear from the name as presented here or many of the reviews, but you should know before going in, this is a Chocolate-themed restaurant. Desserts are more plentiful on the menu than anything else.
That said, I got a delicious turkey burger, and the fries were very tasty (with cocoa powder on them). The place was pretty dead the night we were there, but I suspect it is packed at lunch time from mall traffic. Like everything else in Vegas, it is not really as cheap as you would hope.
