Hang on. There is ONE exception. The "Westmorland Farm Shops" services on the M6 at Tebay in Cumbria.
If you're travelling up to/down from Scotland on the M6, there is a services on both sides of the M6, which is actually owned and operated by the farmers that originally owned the land before the M6 was built. Both sites (north and south bound) have greast restaurants plus farm shops - plus northbound have a fantastic hotel, with a really good restaurant.
