[quote="spike"]vegan things weren't labelled, the staff were unhelpful, though fairly polite and efficient - you're not allowed to have guacamole instead of cheese, you have to go without the cheese and pay extra.
I have been in correspondance with Barburrito about this. They said that the guacamole is the most expensive thing on the whole menu and it would not be cost effective to offer it as a replacement for cheese. I responded by saying that the staff should offer extra of something else, like beans, or should have a squirty soya yoghurt sauce, so that cheese-avoiders don't feel like they are missing out.
The response was that at the moment they are trying to keep things as simple as possible, but will be reviewing their menu soon, and will take all customer feedback on board. They also said that they haven't had many comments from vegans and people who can't eat dairy products, so there doesn't seem to be much demand for a replacement.
Therefore, I'd urge people to either email them or fill in a customer response card, asking for a dairy-free replacement to cheese. They only know people are unhappy if we write it down...
