Búsuló Juhász
This is a special spot for high-end Hungarian cuisine, with huge windows to showcase the beautiful views of the trees and city unfolding below. From the outside, it looks a little uninspiring, but the inside is decidedly polished (despite the fake tree) and the food is superb: try the paprika veal stew or the slow-baked duck leg, followed by the “Somlói” sponge cake. There are also soups, pastas, and burgers on the menu, including a deluxe burger with duck liver. The restaurant is a bit out of the way—a 10-minute walk southwest of the Citadella (away from the river) or 15-minute walk northwest of Bartók Béla út—but it's worth the trip.
