I was surprised to see that Langer's, located on Alvarado and 7th, was in fact that one White people restaurant that I've passed by tons of times on the way to Ktown from La Crescenta.
Thick cuts of pastrami, cool crunchy light cole slaw, home made russian dressing and swiss cheese between two pieces of soft rye bread... a m a z i n g. I don't think I'll ever be satisfied with my usual subway ever again. I can't even find the words to describe this experience but I strongly encourage everyone to at least try it once. You will not be disappointed.
It's a bit expensive, $15 per sandwich, but I think it's worth it. Parking kinda sucks and it's in a super sketchy neighborhood but it's all a part of the Langer's experience.
