I got food poising from the Kobe beef burger [that I had cooked well done]. Based on the meals I had that day and night, the burger was the only thing my friend didn't also eat, so...process of elimination points toward the burger. That being said, it tasted good going down...
We also had the buffalo drumettes and the crab tacos. They're actually pretty small, so definitely treat them as appetizers unless you plan to have them to yourself. Stack also serves its condiments in cutesy jars, but they come with a spoon, as if you're supposed to spoon out the amount that you wish to consume each time.
Lighting was a bit dim, but the decor was nice; wooden fixtures as if you were dining in a canyon. Service was so-so...the saving grace? The hostess consistently walking past our table to seat guests.
