I'm not going to do the guess how much question , and I know if we were skint we could have made sandwiches to eat in the car etc , but was out yesterday doing the last of shopping and all cafes were rammed but found a place that was perhaps not at greasy spoon level but certainly not restaurant , maybe more coffee shop. Soup was £8.75 and tea ( teapot for 2 ) was £3.80 each . So £25.10.
Not a big city , ok a tourist area ( Cumbria ) but not national park just on outskirts of normal working town .
Would that be expensive for your area . Soup was tomato & Basil .
