Well... second time there, this time I didn't order online.
I ordered the soft tacos with chicken and they didn't put any beans/rice/vegetables in there. So I asked what's up with that and they told me that they don't put that into the soft tacos.
Hungry like hell I accepted that and paid way too much for way too little. But I did email Chipotle afterwards about this and they told me that that should not have happened, their tacos should have all the regular filling and that they will speak with management there.
But... that's it. No offer of compensation at all, not even 50% off for my next order or something. Which - considering their prices - makes me not want to go there any more. But if you are aware of what I have just described, at least you won't fall for similar nonsense.
