What it's like to eat at the elite spot frequented by Wall Street billionaires where you have to pony up $50,000 to walk in the door

The restaurant at CORE: Club isn't easy to get into, but its certainly a place you want to be - particularly around lunch time.

For starters, you'll need to pony up a $50,000 initiation fee and approximately $17,000 in annual dues to join the elite club's ranks, which include NFL Commissioner Roger Goodell, billionaire fashion entrepreneur J. Christopher Burch, former White House communications director Anthony Scaramucci, and Blackstone Group CEO Stephen Schwarzman.

When we visited on a recent Tuesday around lunchtime, the restaurant was bustling with bigwigs dining on the fine Italian and French-inspired cuisine.

Luckily, CORE: Club founder Jennie Enterprise invited us to join her for lunch. Here's what it was like.
