Le Bistro Nu
It's hard to top the authentic French fare (steak au poivre, sweetbreads with mushroom sauce, sole meunière) at this friendly, intimate, air-conditioned restaurant. Although it's routinely packed until closing, it's also a bit tucked away on an alley in a neighborhood that isn't exactly upscale and where parking can be hard to come by, so it's best to take a taxi at night. The prix-fixe menu is a very good value, as are many of the bottles on the wine list.
