I've seen and or eaten about all of the mentioned burger places in this thread, by far the best burger place is In & Out.........double double, if you've had one you know what I'm talking about! If these were franchised, I'd buy 6 and put them in the Chattanooga area.
Im burned out on the double double animal style (in -n- out) so I went with A & W with that mushroom swiss thing they have...dripping with fatty goodness.
Cant beat those fresh fries from in -n- out though...it was a potato like 3 minutes ago!!
