I've tried those "All you can eat" Korean BBQ restaurants.. They can be fun but I would classify Ave Seoul within a superior category.
Their dishes taste freshness and their meals feel like home cooking. I never ordered a mealthat came out too oily or overcooked. I've had their bulgogi bibimbap (served in a hot stone) and let me tell ya.. It is on point son! It does remind me of my trip when I visited Korea.
Located near in between Station Côte-Vertu and Du Collège, if you're using public transportation, you'll have no issues getting there. By car, finding a parking spots could be tricky on Decarie, anyhow.. I'm sure you'll find your way :)
Definitely recommended! Delicious Korean comfort food :)
