Rialto Score 8.5+

A Nobu hotel. Book this hotel direct through Rialto at the VIP rate for benefits that can include priority room upgrades, hotel credits, and more.

Nobu Hotel London Portman Square embraces the brand’s minimalist-aesthetic and iconic Japanese-Peruvian fare, yet has a distinctly British vibe. Many of the 243 rooms and suites feature private balconies with views of the chic Marylebone neighborhood, while daily Afternoon Tea treats guests to a local tradition with a signature spin (think lychee-rose tea and Hojicha cheesecakes). There’s also a Nobu Pilates Reformer studio, the world’s first, a hybrid of classic Pilates and high-intensity training.
