We have a new banh mi shop opening in West Roxbury on Tuesday 5/29 (pending final inspection), Banh Mi Ngon at 1759 Centre St. It's located next to Christo's Pizza and on the same block as the recently opened Red-Eyed Pig BBQ and Los Amigos Burritos (the 4th new resto in WR in the last 6 months and 7th in the last year, including Just Baked, Lean Works, Sticky Rice Cafe and Porter Cafe). Van Tang and her husband Tu Vu are newcomers to the restaurant scene but are working with some friends who own Le's in Chestnut Hill. The menu (which I'll try to scan and post) is small but interesting, with most sandwiches in the $4 range, and some apps and drinks (Vietnamese coffee, smoothies).
Looking forward to hearing reviews. I'll be in line there next Tuesday.
