My girl is from Japan and she offered to cook dinner for me when we first started dating over a year ago. I've been hooked since!
Even though this is a "Korean Supermarket" they carry Japanese and Chinese food products and other goods. Every time we feel like doing sushi, but not all you can eat, this is the first place we hit up for sushi grade fish. They have a small section stocked with salmon, tuna, and a third fish that isn't coming to mind. If you want more selection you'll have to go down to the display case where they hold the yellow tail, squid, octopus and whatever other sashimi they managed to get that day.
While their fresh seafood leaves something to be desired, their frozen seafood is extensive and well stocked (they always have soft shell crab) Their produce is also very fresh and only a few times they didn't have what we were looking for.
