I have seen the banh mi light, and am still just kind sorta a convert to the zealotry. It's a damn fine sandwich. I will give you that much. the atmosphere has all the personality of a hospital cafeteria, but the price was a screaming deal.
I really don't care for the cash only policy, but I understand it helps keep those prices at a rock bottom level. Personal pet peeve.
The baguette they use is chewy and toothsome, but there was way too much of a bread-to-filling ratio for my tastes. All the meaty bits they toss in there are also pretty fantastic. If you think you don't like head cheese or liver pate, try the number one and get back to me. It's got both in spades and manages to stay delicious. The cilantro and veggies they toss on the sammich also balance it all into a harmonious French-Vietnamese delight.
Too bad it's in Chandler. The valley seriously needs more banh mi and less pho.
