On your way to Dolores and don't want to endure the claustrophobic counter at bi-rite? Give this place a try instead - you will not regret it. The Korean steak or katsu will warp the way your mind perceives the word sandwich.
Agreed, this place is awesome. It's a pretty tiny liquor store/deli on Valencia at 19th. Really great sandwiches and a nice thing to bring to Dolores (along with Ike's) on a warm(ish) day.
