The Lanes are what makes Norwich feel like a real city with a real identity. Narrow streets packed with independent bookshops, record stores, specialist coffee, and the kind of businesses that exist because their owners actually care about them, it's everything that town centres in the rest of England have slowly lost.
Come on a weekday for the most relaxed version of it, or a Saturday when the energy builds and the cafés fill up. Either way, leave hours not minutes.
