Traditional Hungarian restaurants offer tasty food, often accompanied by traditional Gipsy musicians, who come to your table to play Hungarian tunes directly into your ear.
Citadel is truly spectacular, an absolute must see if you visit Budapest. Actually, I consider it to be one of Budapest's top three attractions. Also, not just Citadel itself is great, but also, being at the top of the Gellert hill, it provides a phenomenal panoramic view of Budapest. Definitely check it out.
