The MAINE Mayfair Bar & Restaurant

You descend into Medici Courtyard expecting another soulless Mayfair operation, but The MAINE surprises you—it's got warmth. The basement space strikes that difficult balance between polished and unpretentious, with dark wood, moody lighting, and enough buzz to feel alive without being intrusive. It's American comfort done properly: dry-aged steaks that don't mess about, fresh fish, and the kind of cocktail programme where they clearly know what they're doing rather than just following trends. The sort of place where business lunches don't feel like penance and weekend dinners actually feel special.
