That's exactly what I did for dinner last night!
I went to our local Taco Bell, as I often have. They were pretty busy but had a full crew working. Last night I had an unusual order- i.e. a lot of take this off- type things. I wasn't sure how it would go!
I made my order and to feed 3 adults and 1 child (less than 2 years old) it only cost about $6! I love their value menu! A particular favorite of mine right now is their Cheesy Bean and Rice Burrito! Right now at my location it only costs 99 cents too! I did learn, that if you ask for no onions, the tomatoes are included because it's a Fresca sauce.
I did ask for no onions and even on the Cheesy Bean and Rice Burrito I asked for no beans. When I got home and unpacked the meal- it was perfect! They created everything just as I ordered it!
I have learned from previous experience (and this is true at many fast food restaurants- I'm not sure why) but I go in and ask for carry out. I have found that by going through the drive- thru, I don't get as good of quality. So while I get annoyed that at this location I have to get out and walk in to order and carry out, I do find I get MUCH better quality.
I have had one issue with an order probably a year back and I called them (the poor quality wasn't found till we got home and opened it). The manager quickly made the order right and gave me a little extra food for my troubles.
