Went on a Saturday night. It looked very busy, but the wait was not that long; maybe around 15 minutes.
The concept is simple: you have an option of soup base and can add extra meat to it. They serve you a tray of side dishes, a bowl of boiling soup, and a bowl of rice noodles. You also have the option of adding extra noodles for free, although just the original serving of noodles was enough for me.
The soup tasted great and stayed hot for a long time, so if you finished your first bowl and were to get an extra serving of noodles it would still be hot by then.
The bill for 3 people came around $50. We ordered a bowl of noodles for each of us, and two appetizer dishes.
