To Eat Steeplegate Tea Room is right beside the cathedral. Light lunches and baked potatoes from 2.20 are available. There's a wide range of teas and coffees here. It's closed on Monday and Tuesday. Totally non-smoking, it has good vegetarian choices.
Eels are a local delicacy served in several of the restaurants.
It seems more like the comfortable house of a friend than a restaurant, but the food is excellent. Main dishes are all about 12. It's open daily except Sunday.
