An airstream travel trailer with dynamite burgers on a challah hot dog roll. The burger is very good and you fill out your order form and 5 mins later a custom burger appears. $5.50 for burger +.50 for cheese. He has fries too. The asian burger was getting good reviews. I'll try it next time. At these prices I expect the Boagman to chime in shortly.
Because it's a trailer it moves around and today was at RobotGarage 637 S. Eton in Birmingham. Very fun.
