After learning from this board that Little Paris has banh mi, I made a mental note to visit this place. I've now been there twice and think I have a good grasp of the place.
It's a really simple cafe/restaurant/take-out place. Lots of Vientamese ready-made food on the counter that you can see before you buy. The prices are so cheap, all around two dollars. Their bahn mi are also cheap, two dollars for the bbq chicken and pork, and $1.80 for the pork pate and mixed meats. The sandwiches come in big French rolls. Not as crusty as Saigon Sandwiches's bread, but that can be a good point in my opinion. The flavor of the sandwich is not as good as Saigon, a bit dry, but overall good and given the lack of bahn mi choices in this part of town, I don't mind spending two bucks for the sandwiches.
They also have a menu that you can dine-in. So far I've only tried their #8, which is a spicy beef and pork rice noodle soup. The soup is basically like pho, but brown instead of clear in color. The flavors aren't too developed, but doctored it up with a bit basil and lime and peppers, it's still a good bowl.
Another major attraction of Little Paris is their buy one get one free pearl drinks. But be aware that their "one free" drink is limited to the Thai flavor tea. You buy one regular any flavor you want and get a Thai flavor free. The price for one is same as other pearl places. But unless you bring a friend who is willing to have the Thai flavor one, the deal isn't really a deal.
I really like Little Paris. It's not fancy, it's not complicated, just simple Vietnamese food.
