Definitely a must visit for AYCE Korean BBQ in Montreal. Tianxia has better quality and more variety of meat than other places like Seoul Chako. For example, I find that Seoul Chako sometimes over-marinate their meat. Tianxia also offers free soft drinks in its AYCE price. My only criticism is that the place is a bit small so it can't accommodate large groups, and for a fun activity like Korean BBQ (where you cook the meat yourself), you want to go in large groups.
