espite the name, anorexics should stay away from this unassuming though well-appointed Greek resto, tucked away on Bernard street; their diets will go to hell (diets?). From the Greek for appetite, Orexi serves ample, exacting traditional fare with a slightly-upscale bent. The space is inviting, but in that don't-spill-anything way. With kebabs, tzatziki, and words that end in "os," it has an authentic air. Having expanded since opening, Orexi can accommodate its ever-growing crowd of regulars, as well as newbies of varying sizes. Bulimics are welcome. -S.T.
