Nicknamed 'Amsterdam's living room', this splendid art nouveau 1902 grand café is in the Amsterdam American Hotel. Its huge stained-glass windows overlook Leidseplein; within, it's all potted palms, whirring fans and dizzyingly high ceilings. High teas (noon to 5pm; €26.50) are especially atmospheric; you must book 24 hours ahead.
The terrace is popular for cocktails on summer evenings.
