Desserts and drinks - especially scotch - put the sparkle on a solid menu. Walking in can work, but reservations are advisable for this Mission destination. It's hard to go wrong ordering and the staff are extremely helpful.
Train-booth style tables in the back have curtain enclosures and are significantly quieter than other tables... not to mention most restaurants in SF :)
