The level of competition is fierce. I think it's safe to say, "It's a dogfish eat dogfish world."
Apparently the owners of Taro Sushi and Teryaki on Washington Blvd. are oblivious to these cutthroat conditions. Sure, they offer their customers the comfort of air conditioning, but they've done nothing to eliminate 'B' rating so conspicuously displayed in the window.
A 'B' rating can only indicate dirty or vermin-filled conditions in the food preparation area. I don't know about you, but for me raw fish and bad hygiene just don't go together. Anymore than Sara Palin goes together with nuanced geo-political analysis.
