How do you get to know someone that can get you in? Probably pretty impossible huh? I think your signature is pretty funny sediment.
Well, it helps to be in the area. People who own businesses and sell stuff to people who can be impressed by such things.
Another way: work for a company that has membership. And, you'll have to do the butt-kissing jobs like selling and wooing clients, etc. But then, you won't get to enjoy Club 33 as much as you'd have to make sure your clients are impressed. I.e., it's a job, but with a perk.
Mostly you'll need some luck.
Last thing: there are members who auction off, for charity, the privilege of dining at Club 33. It's usually pretty expensive.
Thanks about the sig line, too.
