I have only been here for the AYCE Hot Pot. For about $20, you get unlimited hot pot and soda. You can choose two broths from a decent list, some broth bases require extra payment, I have only tried their basic broths. The one with the duck egg and cilantro is a bit bland and the satay broth base is too salty and has a weird taste I can't pin point.
However the broth being bland/weird doesn't bother me a lot since they provide a lot of condiments to make your own dipping sauce, hot pot to me is all about the ingredients and dipping sauce anyways. What bothers me is stale food. I love watercress, especially in hot pot. 3 times I were there everything went smoothly but 2 other times the watercress had a lot of yellowing, which means that it is pretty stale and is rotting.
If they were consistent with the freshness of ingredients I would patronize them more often due to the convenient location, but it is a crap shoot, so I would only go if I desperately wanted hot pot and is too lazy to go to Chinatown.
