This is my favorite restaurant in Phoenix/Scottsdale by far. I have been dining at AZ88 at least once every couple months since 2001. The thing that impresses me most is the consistency of the food. I usually order one of a my usual sandwiches (Picnic Chicken or BLT) and every time it is delicious. And the waffle fries are probably the best fries I've had anywhere. They are literally to die for. Service is always pretty good, invariably some nights when they're busy it can be slower than other nights, but overall I've never once had bad service. There's a DJ up in the rafters and they rotate an always-interesting art display through the place every few months.
AZ88 has a great vibe and atmosphere. It feels like it should be in Miami instead of Scottsdale, and the crowd is usually more trendy and upscale than the douchebaggery spotted elsewhere in Scottsdale. I feel like I'm on a mini-vacation when I'm dining there.
I've tried several items from the menu over the years and everything has been excellent. Drinks are the strongest in town by far. My girl usually gets one of the martinis, which are super strong and HUGE. I keep it simple with a mixed drink (vodka/sprite or Captain/diet) and they bring a glass full of ice and liquor and a separate small can or mini-bottle of sprite or Coke.
AZ88 will continue to be my go-to restaurant anytime friends are in town or we want to just have a relaxing enjoyable "night on the town" that is guaranteed to start off right with a great dinner.
