City Social pairs sublime skyscraper views from its 24th-floor digs with delicate Michelin-starred cuisine. The interior is all art deco–inspired low-lit glamour. If you don't want to splash out on the full menu, opt for the bar, Social 24, which has longer hours and a compelling menu of nibbles (don't miss the goats'-cheese churros with locally sourced truffle-infused honey).
Bookings are essential; expect airport-style security before you can get in the lift.
