As someone who actually has looked into a vegan/veggie commercial venture, I can say it was deemed financially unfeasible in Stafford, simply isn't the market for it here. We looked (and still wistfully glance) into the idea of setting up a small catering van for it, but it would be a labour of love, not profit, and thus we couldn't reconcile losing our jobs over.
Good luck in the search, if you do find somewhere let us know!
I really must try the bean encounter. Love coffee and the veggie burger looks tasty!
