When I lived in Quebec City I used to come here often to stock up on different kinds of instant noodles. The selection is HUGE and the prices are really low. Some of my favorites are Myojo Ippei-Chan Yakisoba Cup, Paldo Cheese Ramyun and Sapporo Ichiban Tonkotsu Ramen. Sometimes it can be a bit difficult to tell what the flavors are because the packaging isn't always translated but it's fun to randomly try new ones. I've also been able to buy here the Internet famous Samyang Buldak Bokkeum Myeon noodles from the Fire Noodle Challenge (look it up on YouTube if you're curious).
Since then I've moved to Montreal and actually live close to this store so I've started to explore the perishable goods aisles too. There's a lot of frozen dumpling options and frozen meat especially beef, pork and some lamb. I haven't tried it yet, but I want to use the shabu shabu meat to make gyudon (Japanese beef bowl). They also have mochi ice cream and a few other frozen treats. So far, I've been able to find any ingredient I needed to make Japanese dishes: okonomiyaki and takoyaki flour, wasabi, curry roux mixes, sauces, etc. They also have a small section with prepared dishes. I've only tried the tuna and beef onigiri (triangle sushi as they call it) and I thought they were just alright.
From my review you can tell that I'm mostly into Japanese food, but they have a lot of Korean food products as well.
