University Settlement is celebrating a big anniversary this weekend and they’re inviting the whole community to join in the fun. To mark 125 years serving the Lower East Side, the large social service organization is hosting a block party, on Eldridge Street, between Rivington and Delancey. There will be a DJ, performances, face painting, arts & crafts and lots of food. The event will be held tomorrow from 10 a.m. to 3 p.m. For more info, visit University Settlement’s web site.
