Only been once. Ordered the volcano nachos and split them with a girlfriend.
plusses: HUUUUUGE nachos, with all the toppings you can imagine. Both of us ate it for dinner and couldn't finish it. It was really good though. Shredded AND liquid cheese?? mmm. Signature mixed drinks were tasty.
minuses: they charge you if you want extra salsa (???), and it was INSANELY loud in there. i had to basically cuddle up next to my friend just to hear what she was saying, and even then I repeated the word "what??" about 892343 times. This probably makes me a crotchety old woman, but DAMN does it really need to be so loud that i can't enjoy a conversation??
Would be good for a party-evening, but otherwise I probably won't go back.
