Some places are more dangerous than others. I’ve been on a cruise, from California to Mexico. We stopped in various places inc Acupulco. We hired a driver for some sightseeing and we asked the driver to take us to a restaurant she would eat at. It was cheap and delicious. Crossing the border at Tijuana and San Diego is pretty safe and by thousands if people every day for a day trip. I don’t understand why the hotel wouldn’t have some Mexican food. But, you are right, there is good Mexican food in California. The fishy chef, Rick Stein, had some good travel and food programmes filmed in Mexico a while ago. I make my own fish tacos at home, salsa and guacamole.
