I've not toured with Frank but there seems to be many positive comments about him in the Destinations -> Mexico section of CruiseMates.

I used him several years ago and it was great, we went to lots of places but my favorite was a little restaurant tucked into the woods of the Rain Forest. I did not sure him the last time and winged it just getting a van at the port. It was good as well but not as good as Mazatlan Franks. I would not hestitate to use him again.
