Zenith

Zenith takes brunch to its most indulgent extreme, with reviewers describing it as the kind of place where restraint gives way to genuine excess — the Oreo pancakes are the emblematic dish. A 4.7 rating across more than 6,700 reviews and a near-perfect must-see score mark it as one of the most visited brunch spots along Gran Via, while its very low hidden-gem score confirms it's a well-known destination rather than a quiet find. High trendy and aesthetic scores fit a photogenic, dessert-forward menu built for social sharing. Walk-ins are reportedly accommodated even without a reservation, though booking is generally recommended.
