The Met questions

I’m seeing a concert (Peach Pit) in May at the Met, had a couple questions regarding the venue! I got Grand Salle box seats, I’ve heard they have their own bathrooms and bar? Also waitstaff? I didn’t get any VIP tickets, was wondering if that’s only for VIP. On my ticket it also says VIP Broad st for entrance, does that mean I can park on Broad? Or if there’s another place that’s better let me know! Thank you!
