Arizona definitely lack cool spots, but luckily they have The Vig. The venue has a nice patio area--perfect for warmer nights, but the inside tables are fine too.
My friends brought me on a Sunday night where all their bottle wines are 50%off... which is pretty awesome. The service was friendly and the food was legit. Try the "Good ol' Steak Salad" and Crabmeat Artichoke dip!
btw the valet is $3.
