I would like to share my list of places, restaurants and activities in Budapest what you shouldn't miss while visiting.
There's not enough available space here on RS to write all.
You can find a list of the main sights, best museums and activities, very nice cafes, pastry shops and restaurants, bars, pubs and clubs and everything else you might need, when visiting Budapest here:

Hope it helps you to get the best out of the city!
