I gave up on Roblaw's and started going to the local Polish grocery store. I might not know what all the pickled vegetables are but it's cheaper and I support someone local.
The 'wasabi' you get at most sushi joints is actually just a coloured horseradish paste. Real wasabi is a different plant (but it's still a type of radish) and far more expensive. It's also grated fresh on your dish as the flavour dissipates very fast.
