A restaurant located right in front of Danube River. It has 1 of the best views to offer, as you can see the city light view at night with Buda Castle, which is 1 of the icons of Budapest. The restaurant has indoors & outdoors. It has an amazing interior on the inside, and has a very cozy ambience, great for dining. If you want to fully enjoy the view, you can try choosing the outdoor seating. Reservations are highly recommended as their seats may not be fully available when walking in.
As for the foods, they are on the pricier side, as they serve fine dining meals. But all their flavors are top notch, so its worth it, although it can be improved slightly for the price they set up. The staff here are very friendly and helpful, as they make sure we fully enjoy our dining experience. Highly recommended in Budapest.
