This is a concept that could do some serious work nationally -- banh mi is a nice counterpoint to the Mexican and burger fare clogging our nation's highways, byways, and arteries.
Although sandwiches are their signature menu items, offerings like the wok’d bowls (filled with fried rice or drunken noodles) should keep the people behind Pei Wei up at night. To top it off, they have iced Vietnamese coffee, beer, and frozen drinks.
Most importantly, the price point is reasonable: the majority of their sandwiches are just $6.95, and offer plenty of flavor for the money. I'd put my money on there being more than just one or two Banh Shops opening in the next few years.
David Maez covers the Dallas scene for Thrillist and loves banh mi more than your Mom. Follow him at @davidfmaez because he's a righteous dude.
