Pedro's cantina is a gem of a bar right across the street from AT&T Ball Park.
On game days you will find this place very crowded however usually this is a great bar for after work drinks or a quick lunch beer.

Pedros offers $13 Valey Parking in conjunction with Momos and Pete's Tavern - both next door. Not available on game days.
