There is this great little place in Imperial Beach on the Southside of San Diego called Doggos Gus. Tiny little place. They make the best hotdogs ever. It was great, I could walk across the street from my hotel and go get the best hotdog for $7. I had about 10 of them on our trip.
This was my favorite:
Bacon wrapped with braised pork, grilled onions, Pico, Chipotle & Avacado Crema on top.
