My lemon drink was more like a regular lemon soda. It wasn't salty and sweet as most Vietnamese lemonades are: no sour plum, no salt.
My friend and I asked about vegetarian options before we ordered, and the server said she could make anything vegetarian. That always makes me suspicious, but I didn't think much of it. We ordered 2 different tofu vermicelli dishes, but when they came out they were EXACTLY the same, even though the server insisted on pointing out that one had coconut milk, when clearly it did not.
It took a long time to settle our bill, as the server was having an argument on the phone with someone the whole time. That was really annoying. I would not go back to this place or recommend it to anyone.
