After being in town for 2 weeks I was craving a good burger. Went with a colleague after a morning of sight seeing and was very pleasantly surprised.
Budapest is a great food town but unfortunately not really for good steak or burgers if you are craving one this is the place.
Additionally the building is a marvelous venue and is a sight to be seen as well as a great view while sitting on the terrace and watching the world go bye and the magnificent view across the river to Castle area.
So if you craving a burger and want a beautiful experience do yourself the favor and go here.
