Sometimes you just need to eat raw fish and drink beer. It's not a fancy or a pretentious thing. And it need not be expensive. It just needs to happen.Thank god for this little counter. For $10.95, the congenial chef, Michio, will fix you up with a tray of the old standards (octopus, salmon, tuna, shrimp, etc.). Another three bucks will get you a beer.If you want something simple and hearty, order a plate of Japanese curry. It'll fill you right up for less than five bucks. But if the freshness and quality of the fish strikes your fancy — and it will — push the envelope. Try a ceviche roll for another six bucks. Or do yourself a favor and get the steamed monkfish liver: Japanese foie gras, Michio calls it. The tender pink substance melts on the tongue in a kind of flavor ecstasy. Just tell him to cut you off at whatever you're willing to spare.
