Some synagogues do, but some don't.
They had feasts where they ate food and played music.

Shavuot is recognized as a festival by all branches of Judaism, Orthodox, Reform, Conserviative. However, of the three pilgrimage festivals, it is the most frequently ignored. (Despite the good food, since cheesecake is a traditioinal food for Shavuot.) I have been to Orthodox synagogues where hardly anyone showed up for Shavuot, and I have been to Reform synagogues that were crowded on Shavuot. Even so it is probable that more Orthodox Jews take Shavuot seriously.
yes, heaps. food festivals, music festivals, new year's eve concerts, autumn and winter festivals.
Some of them do.
