By day Ministerium is a busy restaurant on Libon's main square, Praça do Comércio, whilst by night it turns into a nightclub. We visited during the day...twice...on a 24-hour trip to Lisbon. So that alone tells you just how good the food and cocktails were at this place. It isn't often I go somewhere more than once when I'm travelling as I love experiencing as many different restaurants as possible, but this place was so good that on the Sunday we had two lunches just so we could come back to Ministerium.
