"...arguably the best Deli in SoCal."
Only for people who have never been to Cantor's or Brent's.
Nate & Al's is *way* more reputation than quality...and has become too much of a white-bread chain. There are not *bad*, but certainly not the best.
Brent's has the best Corned Beef. Langer's has the best Pastrami & Rye Bread.
We could go through the other Deli specialties and never find Nate & Al's on the list...save for having the longest waits in their fashionable locations.
