Everyone in our group agreed that this was a great experience. We were very impressed with the food, especially our first stop--excellent authentic tacos! We were very happy that one of our food stops was a food truck for a Sonoran hot dog, something we had wanted to try. It exceeded our expectations!
Biking was a great way to see South Tucson and we definitely needed Jimmy's guidance to find our way around and give us some interesting background on the area. It was a very nice, easy ride.
The only recommendation I have is to give more time at each stop and spread it out a bit. I felt a bit rushed at each stop, gobbling up our food. The first two stops were on the same block, so we ate two tacos, a Sonoran hotdog, and a can of pop in about 20 minutes.
