Serious Eats - seriouseats.com

While I absolutely love the cuisine of France, Italy, and especially Spain, I never went to a country with a particular meal in mind until I went to Argentina on a business trip many years ago. I had tasted Argentine beef while working on a project, and leading up to the trip to Buenos Aires, all I could think about was having a steak dinner when I arrived. I have to say, that meal at La Cabrera exceeded my expectations.

Since stuffed sopaipillas made the cut, I just have to throw my 2 cents in for the stuffed sopaipillas at El Rialto just off the plaza in Las Vegas, New Mexico. My mom lives in Santa Fe, and every time I visit her, we make the drive out to Las Vegas. Yum! Those stuffed sopaipillas are one of the few foods I crave!

Glad to see San Diego represented in the comments. We're closer to Mexico, and definitely closer to the fresh fish (we fish for yellowtail and albacore right off the Coronado Islands every year, and the Dorado (Mahi-Mahi) make it to San Diego first when the water temperature is warm).

Some great spots mentioned in the comments above - South Beach is really good, but I always go for some of their other dishes - like wahoo, thresher shark, or mahi-mahi platters.

Bay Park Fish Company is very good, as well as Taco Surf in Pacific Beach, Las Olas in Cardiff by the Sea, and the Del Mar Brigantine.

However, in my humble opinion, the best fish tacos that I've had in a U.S. restaurant are from Mariscos Mazatlan in Chula Vista (south San Diego County). This is the fish taco that you dream of!

That said, we have a house about 30 KM south of San Felipe in Baja. San Felipe is where Ralph Rubio of the Rubio's chain got the inspiration for his business. There are numerous taco stands that serve up great fish tacos there. You just need to be vigilant about food safety, but I've eaten many times at a couple of stands where all the asaderos are in town (by the arch), and the fish tacos are phenomenal!
