Tucked away in the corner is this small restaurant (which accepts credits cards) that serves some unique stuff (various offal, hot pots, seafood, etc.), although it is not clear what the prices are. Interested people must inquire, although they don't seem to speak much English.
I ordered some spring rolls and bun cha hanoi (it's #8 on their menu, called bun cha bay lo). Bun cha hanoi are grilled pork, pork patties, and fish served in a bowl of hot fish sauce, accompanied by sides of herbs and rice noodles. One can dip the noodles and herbs in the bowl of fish sauce and eat it with some of the meat, or you can dump some noodles and herbs in another bowl, spoon some fish sauce and meat on top of the noodles/herbs and eat it. I did the latter. You are eating the herbs more or less raw since the fish sauce isn't hot enough like a bowl of pho to cook the herbs. This is certainly a different experience. With the spring rolls, it was $12 (after tax but no tip).
