Ground Zero, couple of things...
1/ I am not from NYC. But I remember where I was on the day. Yes it is a military term, but for me a bit too raw for the name of a night club.
2/ Bottle service, WTF??? they make less fuss when the Vince Lombardy trophy is presented. Bring a bottle some glasses and ice, i don't need it to be delivered by the marching band from Cirque du Soleil.
3/ Everyone of you muppets that went there last night is on blast on IG walking down the stairs.
https://www.instagram.com/groundzero_disco/ 4/ I can't remember who the board resident night life expert is, but if he clicks on that link he will be shaking his head. Would it kill you f--kers to lose the t-shirts and put on a pair of pants at night? You are not getting in anywhere in a city looking like that.
Nice looking place, I am sure it would be fun. Name bugs me, could have some discretion, and needs a dress code.
Carry on.
