To be fair, Stafford did once have a very good vegetarian restaurant. It was called Trueman's and was part of what has now become Francesco Land. I think that the owner gave up to become a pilot but I might have dreamed that.
There was a wonderful place in Hanley, for years. A good one in Ironbridge, too, where I spent a birthday.
All those have closed. I wonder whether it might be a result of regular restaurants routinely catering for vegetarians if not always for vegans?
I am old enough to remember being served The Vegetarian Alternative, which contained chicken. I have been asked "We'll, what DO you eat then?" by a waitress and when we went to a fish restaurant once and my partner asked if they would mind doing a green salad for me, the restaurant owner asked all six of us to leave. Vegetarian cafes and restaurants were like refuges then.
Now, thank goodness, I can go pretty much anywhere and eat. Except Madeira. Like you, Lunar, I'd definitely be happiest in a fully vegetarian restaurant but I'm usually the only vegetarian in a group and it would feel a bit much to insist everyone has to eat somewhere vegetarian.
Plus, now, I think it would mean driving to Machynlleth.
