hi: so it's been almost a decade since I did serious time doing fish taco weekends in Baja, lthough I bristle at thinking that LA tacos are better than the real deal. Rosarito is the closest place to the border for fish tacos and Mexican style lobster dinners. For fish tacos look for a roadside stand that is busy or at least tidy and welcoming and if you get a sense that the oil is tired or murky move on along. I am not squeamish in any way, my favorite fish taco stand consisted of a lady chopping the veggies on a beautiful old weathered stump of a log but bad oil will ruin your trip for about 72 hours. When you eat the tacos lean out over your belly so the milky white juice mingling with the grease can drip down on the dust. Now you know you're in fish taco land (try doing that at a Rubios!)
Rosarito is also known for its Mexican style lobster. That mean they deep fry the lobster and serve it family style with beans, rice, tortillas and a TJ style Caeser salad and yes, Caeser salad was invented in TJ. Make yourself a lobster burrito/taco and again, enjoy the butter/grease goodness dripping but this time you'll be sitting down. If the thought of deep fried lobster doesn't work for you you can ask for it to be boiled or baked but you will have to wait longer than anyone else around you.
If you head down to Ensenada, this is fish taco heaven, Go to the large seafood market and all around it there are fish taco stalls. If I remember correctly my favorites were those closest to the entrance to the market.
Somewhere between Rosarito and Ensanada is a hotel called I think, La Fonda, very popular in the 40s with Hollywood stars wanting to get away. It hugs the cliffs above the ocean, and is all pink and stucco. Do a google or look in a travel book. My sister charmed the Mexican chef into taking us into the kitchen showing a whole pig, talking lechon, drinking tequila . . . we were treated very well simply for showing interest the food and this was way back in 88 before food blogs and such.
If you want to contact me at my personal e-mail I can reach into the dusty corners of my mind, I know Baja has changed in the last 10 years but I am sure there is still a lot enjoy.
