Flatiron, Manhattan · bar
The Radio Wave Building is where Nikola Tesla once lived and Patent Pending turns that into a subterranean cocktail cave. You slip through a coffee shop into a candlelit basement where the menu reads like a lab notebook—Energy, Frequency, Descent—and the drinks follow through. There’s a taxidermy pigeon on the wall and the room is dark, a little strange, and dangerously easy to lose a few hours in.
