There's a great new restaurant site called Where the Locals Eat, and lo and behold, they have a review page for Langer's. Their own write-up is very complimentary (thank you!) and it allows users to leave their own reviews behind, as well.
Declaring a favorite Los Angeles deli may be as dangerous as proclaiming love for the Giants in Dodger Stadium. You can say with certainty, however, that since 1947, Angelenos have flocked to Langer's...
It's a nice, well-designed site, so check it out and make sure you let them know what you think of Langer's.
