The Well Bento   The food at this take-out joint is as artfully arranged (even if it is in a Styrofoam container) and as carefully prepared as in a fine restaurant. The fare ranges from macrobiotic to conventional-but-healthier: grilled soy foods, fish or meats, served with nutty brown rice and tahini “gravy” and an exceptional lightly dressed pasta salad. No boxes, bottles, cans or genetically modified foods used.  2570 S. Beretania St., second floor. 941-5261. 10:30 a.m.-9 p.m. daily. No reservations. AX, JCB, MV, VS. Checks accepted. $.
