I am currently taking a summer school class at ASU and this is 5 minutes away. I know if I am a student at ASU, this is a place I will be frequenting.
My order: Footlong with ketchup, chips, and celery salt with fries. Cooked to perfection. Very polite staff and you see them handle your food (which is done in a clean manner). I am extremely glad I found this great hot dog joint this summer.
One complaint: Be aware of the lines. Guarantee of at least 15 people long and takes at least 10 minutes.
