One word: delicious.
Quick, friendly service, clean looking truck and for a hot dog stand an extensive menu. They offer all their selections with a vegetarian dog, which I love! I had the special of the day, it was fresh and hot, served on soft warm flat bread that tasted like it was baked that morning.
I know they travel around the valley, the best location for me to catch them is the Urban Market downtown - they are there Saturday mornings, Wednesday evenings, and for lunch on Fridays.
Will be back this evening for round two!
