I just love this place. First of all you can't get food in Phoenix generally after 10pm and this place cooks until midnight!!! Second of all its great food - although it is a little spendy. Try and hit up some of the happy hour times (sit at the Bar only) also there are sometimes reverse happy hours 11pm-midnight.
This seriously is a great place to take someone on a late night date. PLEASE enter by going down the stairs on the right. It is really cool downstairs. There is also upstairs seating and a bar but downstairs feels like you are in Boston!
They do not provide high chairs or booster seats so get a sitter and leave the kids at home.
Valet parking which I find annoying but it is tough to find parking at times.
Dress code - well its still Phoenix (and warm weather begs for casual) but it wouldn't hurt to step it up a notch.
