Love, love, love. The banh mi here is delicious, and will only cost you $2-$4. While I love the standard banh mi, which contains an assortment of Vietnamese cold cuts, the ones with BBQ pork and chicken are also really good.
There is also an assortment of ready to eat meals, and I got the goi cuon (summer rolls/wraps containing vermicelli, pork/shrimp, and lettuce), which is pretty decent for something that's been sitting in the fridge.
