Lol I went to the Mellon one last year - it was like a high school prom dance event but with 1,000+ late 20s/early 30s yuppies instead. It was complete trash, the catered food was garbage, and I immediately got COVID for the first time right after. I don't remember exactly how much it cost because my pyscho ex bought the tickets for us, but I think it was at least $200 for mine. Good stuff haha
