They totally bungled my attempt to try this.
I ordered it as a box meal and asked that they turn the Burrito Supreme into basically a bean burrito with sour cream (substitute beans for beef, no tomatoes, no lettuce). There is no way they could have thought I was asking them to sub beans for beef on the entire meal because I specifically prefaced it with "On the Burrito Supreme, can I..." and they even asked me to clarify that I did want lettuce and tomato on the taco. Sure enough, it was wrong on the receipt.
A crunchy BEAN taco (YUCK!) and stuffed BEAN Nacho was too much bean for one night so I gave the burrito away.
I hope they didn't also screw up Ichinisan's soft taco supreme that I ordered and delivered without looking inside (it seemed right according to the receipt).
