While I can't speak for or against the food that was, I can tell you that these days El Adobe is serving up some of the most tourist-friendly Mexican-style food in San Juan Capo, and that ain't good. It ain't bad, but it ain't good.
It wasn't good for the ambiance, either. While a lot of the old west charm is still firmly in place, it's often marred by "Dick and Pat Were Here" PotUS worship. Still, if you get a kick out of Dick this is your kind of spot.
It's not mine, but it was worth a larf, and while I don't have much good to say about the Nixons, I will say that in the course of researching a couple of ideas for this piece I ran across this article which contains a letter Nixon wrote to Penny Pincher's Cook Book author Sophie Leavitt praising her for providing those less privileged with a path to better nutrition. I suppose that even the man who said "Oh, when the President does it, that means that it is not illegal" wasn't all bad.
