I eat at Postino's for lunch occasionally and really enjoy it.  It definitely has a bit of counter culture flavor - a few tattoo's showing on staff and a wine bar in a heavily Morman area.  that said, the food is awesome.  The only criticism is the menu's a little short compared to a similar wine bar in Mesa.  The wine is very competitively priced and they have their wine by the glass \"happy hour\" which lasts all afternoon.  The staff is very professional - I haven't had a poor waiting experience.  Everyone chips in so water's always full and empty dishes quickly cleared away.
