Is there any place with a good selection of Asian groceries nearer to Wellesley than the Burlington HMart? A place like Somerville's Reliable Market, for instance. Most of the stuff I'm looking for is Japanese. I know I can cobble together most things from regular grocery stores, but a wider selections and one-stop shopping would be great.
If you know a place that regularly has fresh mackerel and salmon collar, that would be nice too. The guys at Captain Marden's were very confused why I would want to buy either.
