Olive and Sage

Head up Flask Walk in Hampstead and you'll find Olive and Sage doing bagels properly—the kind that have actual chew to them, not those deflated discs you get everywhere else. The spot's got that neighbourhood feel where locals genuinely queue for breakfast, which tells you everything. They're clearly not messing about with the fillings either; you're getting proper combinations that make sense together rather than random posh ingredients thrown on for Instagram.
