I ordered a "World Famous Fish Taco" and a chili-lime salmon taco. My order was ready in a few minutes, although it became obvious that the fish in the former had been cooked long before I ordered it. Usually Rubio's fish is freshly fried, which means it's crispy and hot. This was lukewarm and best and had the texture of a dry sponge. Obviously it had been cooked a while earlier and was just waiting around for an idiot to order one. In this case, I was the idiot.
Fortunately, the chili-lime salmon taco was the opposite: it tasted fresh and was delicious. The salmon was tender and although it was buried under a deluge of toppings - corn, chipotle sauce, and cabbage - they were all great. I certainly wished I'd ordered two of these instead of the regular fish taco.
I will probably return to Rubio's the next time they have a promotion that catches my eye (although not this one), however I am definitely done with them for regular fish tacos when I'm in Pasadena. They may have thought they were saving money by serving me a piece of fish that had been cooked earlier and wasn't even warm, but in the end they lost money, because I won't be returning.
