Dinning rooms at maritime museum

Out for lunch with mum and we ate at the maritime museum dinning rooms, looks lovely on internet but very disappointed with ploughman's lunch for £6
Room was cold and basic, menus were a4 paper and scruffy, chairs hard, very basic surroundings, disappointed as we has passed so many lovely looking places to walk here in Albert Dock, won't be going back, food ok but not worth what we paid
