They had feasts where they ate food and played music.

Feasts and celebrations
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.
Some of them do.
