An atmospheric, candlelit drinking den is open on Friday and Saturday nights at Brunel Museum. Cocktail lovers can get cosy around the campfire with drinks, Greek street food and riverside views this summer. An advance ticket costs a fiver which includes entry to the museum – with an optional guided descent into the underground chamber (maybe do that bit before cocktail hour!). It’s all to raise cash for the new entrance and staircase for Brunel’s underground concert hall.
