Yes, just yes.
Ambiance, food & drinks are a win any day of the week. I've not had problems with service (food has been prompt within reason depending on the amount of customers); the servers are friendly, though I wouldn't classify the service as 'amazing'.
We usually go to Postino for Sunday brunch as a family of 4 (2 adults, 2 kids); the wait is reasonable (20-30 min), and the food is always quality. We also drop in on random week nights for a date night- can't go wrong with the bruschetta board!
Thank you, Postino, for taking care of your Phoenix community.
