The best banh mi in the city. There are options on the menu, but I have never actually looked at it. I order one of two things: a large regular (for myself) or a large vegetarian spicy (for Mr. Vegetarian) which is made w tofu. All the textures are perfectly in alignment - crusty bread, crunchy vegetables, soft pate and cold cuts. It's a great sandwich, and they make them here and ship them to a bunch of other places in the city (including a few of their further-away outlets) so you might be eating their sandwiches and not even know. But the made-fresh are the best.
They will sell you a plain roll for a quarter, if you ask.
The banana cake is great, with the little pot of coconut chutney. Also the fresh rolls are great, and the rice plates with sausage are always good - you can totally just eat them at room temperature for breakfast and be happy there. If you're an adventuresome eater, just try some things. They are pretty much all great.
I tend to go first thing in the morning and have banh mi breakfast. Downside to this is that lots of ingredients and finished sandwiches are coming in and out, so things are always chaotic. Upside is that they do much less retail business then, so if you go in the morning for a while eventually they will recognize you. When they start to recognize you, your sandwich improves (more vegetables, a nicer pate layer).
Fun fact! The guys who own Banh Mi Boys are the sons of the couple who own this and the other Nguyen Huong Foods locations. Yum.
