As far as hotpot goes, I think that this is the only decent one in Montreal so far. Located up on the second floor with ample views of the mean streets of Chinatown, a window seat is almost mandatory for the full experience.
The three most important things for a delicious hotpot are:
-robust broth (so I recommend only ordering their spicy herbal broth)
-fresh vegetables and thin sliced meats
-a well-made dipping sauce
The well-made sauce portion of a good hotpot meal relies solely on you, the patron, to make at the sauce bar. No one is going to hold your hand through this process, but I can attempt to give you a quick recipe for a good one; 2:12 hot chili oil with bits, 2:12 soy sauce, 1:12 sesame oil, 2:12 scallion/chives, 2:12 cilantro (a must have), 1:12 vinegar, 1:12 paste/minced garlic, 1:12 ginger paste. There is also a sesame paste sauce that can be made using diluted sesame paste, but I like spicy.
Don't be afraid of the watercress, and try making a hard boiled egg. The cooked egg is delicious peeled and then dipped into your dipping sauce.
There is also a small buffet portion set up that has things like spring rolls and sesame balls. But, I found these items not to be very fresh. There is also an all-you-can-drink soda and juice fountain that actually has some delicious sweetened soy milk on tap and orange juice.
