Keto Fish Tacos

I love a good taco, c’mon who doesn’t? but these fish tacos are beyond good.  I don’t want to toot my own horn, but these are seriously among the top 5 best fish tacos I’ve ever eaten, and I’ve eaten a lot of tacos.  The seasoning of the fish and the salsa, THE SALSA, really are what take this taco recipe from ordinary to extraordinary.

I have searched  for years to find the ultimate fish taco restaurant.  So far the best I’ve found are from Mateo’s Mexican Grill in Tulum Mexico with an honorable mention to Torchy’s in Austin, TX and White Duck Taco Shop in Asheville, NC. Also Por Que No in Portland Oregon.

Sometime during this year of traveling in our RV, my wife and I have decided to spend some time in a few small(-ish) coastal towns in California, so I’m hoping to find another fish taco joint to add to the list, if you’re from that part of the world or anywhere really that has good fish tacos I’d love to hear your recommendations in the comment section below.
