UK

Once ruled the world. Dinner is still a struggle.

Brick streetscapes, weighty concrete and high-tech architecture. There is no shortage of buildings to see. Survive on fish and chips and meat pies.

Getting around: Group London visits by area. Treat a trip to another city as its own travel day rather than squeezing it into city sightseeing.
Exploring: Separate exterior visits to offices and housing from public access inside. Look for architectural tours as well.
