I live in Manhattan where there are too many good restaurants to choose from and Cape Cod where there are too few. On the Cape,"The Season" has begun and last week we were told there was a 45-minute wait in one mediocre restaurant, the second was too depressing (our favorite bartender - the life of the restaurant - was off). We headed to our only real choice in Chatham -- the Impudent Oyster -- where the food is excellent. We eat there every week when we're on Cape and we really wanted a change. Eyeing the sushi restaurant, Susumi, across the street, we decided to try it. Seemed a little strange to be eating sushi on the Cape, but we were desperate for something different. The entrance is above street level, so you can't see the interior till you enter. We were stunned. It was beautiful; it was sophisticated; it was not what we were expecting. As we waited for our food, my husband and I wondered how a sushi place could make it on the Cape where everyone seems to be looking for the best chowder, the best fried clams, etc. "Well," we agreed, "they're in the right place for fresh fish." Our food arrived -- the sushi was the best we've ever had -- better than the best in Manhattan. They also have Asian dishes which we'll try on our next visit. If you're on Cape, try it -- it's better than 98% of the Cape's restaurants. Susumi -- on Chatham Bars Avenue in Chatham.
