Sydney Sydney is one of the most laid-back of cities--which is no reason not to tear it up on the back of a Hog. Easyrider Motorbike Tours runs 60-minute Harley-Davidson rides around town, including a photo op on Bondi Beach. $85, 011-61/2-9247-2477,easyrider.com.au.
How to guarantee a stellar lunch
It's no surprise the Michelin Man has a spare tire around his middle. The French tire manufacturer's red Michelin Guide has steered diners to Europe's best restaurants for over a century, and its star ratings are the most coveted award in the business. Initially, three stars meant an establishment merited a special trip, two stars that it deserved a detour, one star that you should stop if it was on your way. They're almost uniformly expensive, but the good news is that many also serve lunch, and for a fraction of what a dinner costs. Menus are typically three courses--limited selection of appetizers, main courses, and desserts--a fixed price. (If you'd like a glass of 1961 Château Lafite Rothschild Grand Cru Classe with your lunch, expect to pay extra.) Here are three notable Michelin-starred restaurants. Reservations are essential.
Belgium Chefs Pierre Wynants and son-in-law Lionel Rigolet are the masters behind Comme chez Soi, a three-star Brussels establishment for 25 years. The $84 prix fixe lunch can include ham mousse from the Ardennes; sliced cod with tomato coulis, black salsify, and marjoram, plus a selection from the cheese or dessert menus, perhaps hot soufflé with Roquefort. 23 Place Rouppe; 011-32/2-512-29-21, commechezsoi.be; closed Sunday and Monday, and Wednesday lunch.
England A 50-minute train ride from London's Paddington Station, The Fat Duck has earned accolades for chef Heston Blumenthal's brilliant but humble approach to modern French cuisine. (It earned a third star in 2004, which it retained this year.) The $70 lunch features velouté of fennel with lemon balm and oyster, braised pork belly with Savoy cabbage and lardo from Colonnata, and carrot toffee with butternut ice cream and pumpkin seed oil. High Street, Bray, Berkshire; 011-44/1628-580-333, fatduck.co.uk; closed Monday.
