In the second episode of GQ's Most Expensivest Shit, 2 Chainz samples Le Burger Extravagant from New York's Serendipity 3, which holds the Guinness World Record title for the world's most expensive hamburger. By his own admission, 2 Chainz has a chef with him "at all times" and eats "very well," but never like this.
Some More Choice 2 Chainz quotes:
"This burger right here costs more than your iPhone."
"I always wanted to go in a cave."
When learning the price of kaluga caviar: "That's about a gram." [smirks at camera]
"I'm going to challenge my chef to order some things from a cave. Eileen [his chef, presumably], you gotta go to the cave, baby."
