An exhibition called Art Fanatics can be seen in the Art Hall at the Heroes Square in Budapest between April 3rd and May 23rd. It shows the private collection of several Hungarians. Not to much of a thrill to foreigners maybe, but if you still visit the Heroes Square and need to use the toilet in the basement of the Art Hall, then maybe you could check out the exhibition as well, while there.
