on a recent trip to Saigon Sandwich, i noticed a new place called Cindy's Deli at 601 Larkin @ Eddy. it's on the opposite corner from Saigon. it appears to be a regular Arab corner store with a Vietnamese deli inside. the banh mi are $2 and i highly recommend the bbq pork. the nice thing is that they're made to order, so it's probably easier than at Saigon to get more or less of a particular ingredient. i like a little extra cilantro, for example.
curiously, when i go at lunchtime the sandwiches taste better than later on in the day. a Vietnamese guy with glasses makes them at lunch. very tasty. someone else was behind the counter later on. maybe they don't have the same touch, or maybe it's all in my head.
i prefer the bread at Cindy's to the bread used at Saigon. i also don't always want to brave the crowds at Saigon. Cindy's has bbq pork, bbq beef, chicken, and i think some kind of ham combo. Saigon has a bigger menu.
it's worth checking out sometime if you make regular runs to Saigon. i think it opened 3 months ago. i have a feeling that the guy working at lunchtime might own a vietnamese restaurant around the corner and perhaps works there at night. there's a picture of it on the wall.
