There’s a raft of modern eateries in Warsaw, but you can’t get more cutting edge than taking centre stage inside a city centre castle that doubles as a modern art gallery. In summer you’ll find the best seats outside, touting grandstand views of a park and lake below, though eating inside the post-modern stone-clad interior is by no means second best. The surroundings are faultless, meaning the food has a lot to live up to. It’s not bad, just not memorable, with a selection of creative interpretations of Polish cooking.
