Very taste BBQ! Go here on an empty stomach because it is AYCE for a reason.
Their service is decent although the servers did forget some things. I haven't had Korean BBQ anywhere else in Montreal prior so I have no point of comparison but the meat seemed fresh and flavourful. It's not in the downtown core, kind of out of the way in NDG but I'd say go if you're staying close by - otherwise it's not worth the trek.
They have unlimited soda from the fridge which you get yourself. It's a cozy place if you want to spend some money on good Korean BBQ.
