Pacific Dining Car
6th Street & Witmer, Downtown
Los Angeles, CA
all damned night!
Pricey, but if you're in the mood for an awesome steak, rack of lamb, or surf & turf, this is the joint. There are two locations -- one in Santa Monica (not open all night) and the original location (open ALL NIGHT) in downtown L.A. at 6th St. and Witmer (right next to the hospital).
Good wine list and great bar selection too.
Apparently a great breakfast too, but I always eat dinner when I go.
Everything is a-la-carte, so prepare to spend some bucks. But if you want great service and upscale food at 4:00 am, you can't get better than this at that hour...
