What would be the sort of clientelle? Old scone munchers, active people like bikers etc, or studenty laptop users / coffee lovers?
I have often thought that there is space for an urban feeling coffee house in the country. I like that kind of “spend the afternoon or evening” type atmosphere you get in a god city coffee house. Ifg thats whats needed, then free wifi is a must, dimmable lights, comfy sofas as well as proper sit at tables so people needing the type seriously can. Displays from local artists are good, as well as gigs by small bands etc.
Staff need to be friendly too and not too cliquey.
My prefered place has prepacked sandwiches, and two hot dishes every day, one soup and one stew, always veggie, but usually curry or goulash, home made and very tasty, served with wholemeal bread. They cook big batches and store in the fridge in microwaveable containers and heat as needed. All seems simple and works very well. Key thing is they do a couple of things well and dont do a lot.
