I would love to try them - I love shrimp/fish tacos of all kinds, so I am intrigued.
However, they have an "avocado sauce" and I have a BAD reaction when I eat avocados... random and copious vomiting. NOT fun. When I asked about it, the Taco Bell order-taker offered to leave the avocado sauce off for me, but she didn't offer to sub any other sauce, and I was not sure what to ask for. It seemed to me that they would be fairly dry sans sauce, so I just skipped it and ordered my normal burrito.
