This Cajun/American/Asian amalgam is run by the folks at On Teur, another favorite eatery in Midtown. Succulent sandwiches, salads, and fish dishes are specialties. The lively decor, with its floor-to-ceiling portraits of blues greats B.B. King and W. C. Handy, is pure Delta funk -- a cross between Highway 61 and Route 66. But one bite of the creamy, Cajun crawfish macaroni-and-cheese, and you'll think you've died and gone to heaven.
