The Vietnamese bakery and deli that New Saigon opened last year locks its doors at 4 p.m., so you'll need to plan ahead. But you can order two banh mi sandwiches and get change back from a ten — so holding onto them until dinner is mostly a matter of self-control. Then, when the moment strikes, that crusty baguette — the freshest in town — filled with crunchy vegetables, pungent cilantro and your choice of marinated, grilled or cured meats will disappear like a guinea pig confronted by a python. The second sandwich is clearly too much food, but saving it for later just means thinking about nothing but banh mi until then. Besides, order two and you'll be able to try more of the meat fillings, which include sweet, fatty pork belly; barbecued beef; grilled chicken; even sardines. You'll only break between bites to quench the fire from the raw slices of jalapeño. And at this price, getting a boba smoothie to do that job won't break the bank.
