London 
Map
Classic British seafood in the bank district, only open weekday lunches, no reservations, pure London.
Unbelievably swank hotel in a century old bank building with half a dozen food & beverage options on the ground floor alone - go at night for live music on a marble pedestal in the middle of the enormous lobby, it's a celebration!
14th-century market with an ornate Victorian roof, you may recognize it from Harry Potter. The Lamb Tavern is a great place to great a pint and people watch.
Covered market since the 12th century - bustling and vibrant with prepared foods, produce, restaurants, etc
Enormous dream of a brutalist compound, photogenic and well cared for with gardens, water, a performing arts center, cinema, and a great gift shop.
