Park Restaurant

You're walking into the Royal Lancaster's dining room on Lancaster Terrace, where floor-to-ceiling windows overlook Hyde Park and the breakfast menu actually takes itself seriously. It's the kind of place where they'll do your eggs properly—fried, poached, scrambled, however you want them—alongside proper pastries and fresh juice. The room itself feels properly grown-up without being stuffy; the sort of space you'd go for a leisurely weekend breakfast with someone you actually want to spend time with, not just somewhere to grab toast and run.
