Who cares about a little fog (okay, a lot of fog) when there’s so much to do in San Francisco? By day, explore Fisherman’s Wharf and the Aquarium of the Bay, ride a cable car, and stroll around the Presidio; by night, have a fabulous dinner (at a Michelin-starred restaurant or a tiny place in Chinatown), then hit some of the best clubs on the West Coast.

Unassuming Brussels is the capital of Belgium, Flanders and Europe. Medieval Grand-Place is indeed grand, with many 17th-century buildings and daily flower markets. Reopened in 2006, the Atomium, Brussels' Eiffel Tower, provides great views, both inside and out. Architecture fans should visit the Musée Horta, home of Belgian master architect Victor Horta. St Gery's clubs and bars are packed all year round. Seafood eateries abound in Ste Catherine. Exploring the narrow streets on foot is more fun than getting snarled up in traffic.

Many people travel through Frankfurt for business, as it's a major transportation hub and an industrial and financial metropolis. Of course we know that business travellers hate to have any fun on the road (wink), but it's worth lingering in Frankfurt if you can. The 2,000-year-old city has much to offer: skyscrapers, the Main River, a famous opera house, thriving theatre district, zoo, pedestrian shopping street, parks, scores of bars and dance clubs, and more than 50 museums.

Sitting on the edge of the Baltic, the modern, cosmopolitan city of Helsinki is the World Design Capital for 2012.

Walking tours of the city centre show layers of history, while modern architecture and cutting-edge style stake the city's claim to the future. Choose Helsinki during its endless summer days or get adventurous on crisp, snowy winter nights.
