Absolutely. I wear my T-Shirt proudly :-) The Fries of course are number one. Next, would be a double-double (Animal Style) with grilled onions as a choice. I like the shakes, but am diabetic. Only if I don't have fries and cheat a little. Otherwise a diet coke.
The service has always been awesome. They are very customer satisfaction orientated. The food in my view is superb with high quality standards. For instance all the handling of the beef is in house. That aren't outsourced. At each location you can watch them make potatoes into fries while standing in line.
They have a history with drag racing too going way back and inclusive of sponsoring professional and sportsman category cars. That gets two thumbs up from me. I think the owner/heiress races still today.
Footnote: Their menu is only burgers, fries, shakes, and beverages.
Let me step back a step. I first was introduced to them back about '73. They had a stand at Irwindale (California) Raceway (Drag Racing). The lines many times went as far as the eye could see. You had to time it when the crowd was in the stands and still the line would be a little long.
