The grill out will involve your typical party favors, although amplified by the Rock & Roll spirit of the venue. Attendees can expect to be drenched in water-fun festivities, dine upon the fine American cuisine Mayday creates, watch summer films and drink craft beers from Bell’s, Bear Republic, Greenflash, Troegs and Northpeak. It’s all kid-friendly until 9 p.m., and at that point the chains are loosened for a Major Rager Dance Party with DJ CSDIV. The party starts at 6 p.m. Saturday, July 21. Mayday, 4227 Spring Grove Ave., Northside. 513-541-0999, maydaynorthside.com.
