I went to Phoenix 2 weeks ago and had to have in n out for sure and fat burgers...where in so cal are you...i used to go to Tommys all the time...mostly at the one in Santa Monica but always hit the original location once a month.
I'm in Lakewood. I normally go to the Tommy's in Norwalk. Whenever I'm out in LA, I always go to the original one though. I think I know what I'll be doing tomorrow....
I also have an in n out literally right up the street from me! Probably a 5 minute walk.
