The venue was gorgeous with a view on the water and castle. The artistic floral arrangements were stunning. The one star Michelin ranked restaurant was part of the Four season hotel. It was ideally located a short walk from the Charles bridge. The service was friendly and efficient. When I came for dinner, Allegro was almost empty. The food wasn't memorable. It was truly over-priced compared to other Michelin ranked restaurants in Europe and the US. I had better tasting and more innovative dishes at restaurants with no stars or Michelin Bib gourmand restaurants. Thus, the likelihood of another visit will be 0. I would suggest to eat at the Bib Gourmand "Le Terroir" in Prague instead.
