Really, if you insist on the Apple Pan and similar dreck then you are missing out on LA best burger deals, to be had at:
B and R old fashion in the strip mall at Cerise and Rosecrans
Fresh and Meatty burger on Florence near 10th, sou th side of the street
Fred's Down Home Burger on 4th and Slauson
All have specials w/drink and fries that will run about 6 bucks. Love Fred's fries in particular.
These are close dopplegangers to the late Meatty Meat burger, and leave most of the stuff discussed on chowhound in the dust (particularly when you factor in prices).
