Very expensive. But you know you'll be paying a premium based on the location. You basically know you will be overcharged before you walk in, so don't be mad when you end up paying about $15 (after taxes are included to be fair) for 3 tacos the size a stick of juicy fruit gum. The burgers seem to be the most fairly priced menu items (from a "you get what you pay for" perspective). I had one of the burgers, and it was quite good. The service was also fine.
An issue I have with this place is the fact that they add an automatic 18% gratuity on your bill if you are in a large group (even if they are separate). I know a lot of places do this, but this is still a real dick policy. I usually tip 20%, so it actually does me a favour.
Overall, a nice place though.
