Stumble through SoHo after last call, and eating options are limited. A guaranteed pre-hangover delight, though, is Js Grill. Located in the MacDintons parking lot, the stand offers big, delicious, greasy burgers, hot dogs and bratwursts all at reasonable prices, especially for a place on South Howard. Its open Thursday, Friday and Saturdays from about 10:30 p.m. to 3:30 a.m. All-around nice guy Jason Ruhe, who owns the grill with his wife Hope Montgomery, typically is the fellow serving the tipsy masses.
