Holy smokes. I get why this place gets such stellar reviews. We went during the heart of the lunch rush right after we landed in Phoenix and as we were in line, they ran out of the fatty brisket. Sadness. When we got up there, I asked the guy cutting the meats if he could find me a fattier piece of the lean brisket and he obliged. We tried the brisket and chopped brisket plate with all four sides and the pecan pie for dessert. Everything was incredible.
The one thing to watch out for is the first option for tip is 20%, which is ridiculous after you've been standing on a line for almost an hour to get your food. I was so happy to finally have the food in front of me that I didn't even notice which button I hit and ended up leaving a $7 tip. After waiting in a massive line for counter service, that's not what the norm should be.
