Visiting the Warehouse Café is a bit like going round to your hippy mate's flat. The veggie café is on the first floor of Birmingham's Friends of the Earth building, so you know you're not in for a microwaved Big Mac. Solar panels heat their water and used vegetable oil becomes fuel for a car that actually runs. The cheap, simple, but very filling food changes daily. Homemade cake and tea for afters complete the perfect meal, wherever you sit on the food chain.
