I happened to catch the tail end of it this April and it was quite enjoyable--good variety of quality hand-made items, some quite unique and others more typical of such fairs, also some edibles like jam and chocolates. Wonderful food booths, each more enticing than the last and I circled them all before deciding I needed a grilled chicken pita-esque thing (not langos, though of course they were well-represented) one day and the other I chose my favorite Hungarian dish, toltott kaposzta (stuffed cabbage). Lots of pastries and desserts and several booths with wine and beer. Food prices were extremely cheap, so it was a good stop for dinner a couple of days for me. Plenty of seating at both picnic tables and some smaller tables. Overall atmosphere was lively and fun, plenty of locals there as well as tourists, excellent people-watching. Perhaps give it 1 to 2 hours to walk through if you get a chance, not hard to do since it goes into the evening hours.
