If you like Vietnamese food, you will love this place. Smack in the middle of Chinatown (unless you know your way around it's a little hard to find), the place is perpetually full of smiling Vietnamese chowing down on stuffed to the brim banh mi sandwiches, big summer rolls (Gỏi cuốn), bubble tea and the like. The place has a couple of tiny tables and long counters against the wall where you stake your claim, latch on to your own bottle of fiery Sriracha, and enjoy. The proprietors and workers speak little to no English, but communication is easy. You simply smile and point to your selection on the colorful menu board. I love this little place. Enjoy.
