I like all the Postino's. They do a wonderful job of revamping old buildings (not that many left in town know for treating down anything old) and turning them into interesting, relaxed restaurants. This place used to be an Art Annex for ASU. Thus the Postino Annex name.
I come here mostly on the exceptionally priced, bottle and board special nights. This location has less couples on dates those nights compared to other Postino's locations and instead is filled with a larger percentage of coeds on girls having wine night out with friends. The patio is my favorite place to sit and looks out at the growing skyscrapers in the area around the ASU football stadium.
The line can get long, so get there right when the special kicks in.
