We've heard Toronto described as "New York City run by the Swiss," and it's true—you can find world-class theatre, shopping and restaurants here, but the sidewalks are clean and the people are friendly. The best place to start is literally at the top—the CN Tower, the tallest freestanding structure in the Western Hemisphere.

If you’re a history buff and a die-hard foodie, Chicago’s your kind of town. Take an architectural-history walking tour, then dine at Alinea (the most celebrated molecular-gastronomy restaurant in the U.S.). And don’t miss the Museum of Science and Industry, the biggest science museum in the Western Hemisphere.

Montreal, c’est si bon! This French-speaking city is considered the cultural capital of Canada, and is a cosmopolitan celebration of Québécois style. A horse-drawn carriage ride around the cobblestone streets and grand buildings of Vieux-Montréal will give you a taste of European flavour. The Basilique Notre-Dame is a confection of stained glass, and the Plateau Mont-Royal district will delight you with its quaint boutiques and cafés. Dig in to a massive plate of poutine to fuel up for a tour of the epic Olympic Park.

The first time you go to New York, go ahead and be a sight-seer—everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighbourhood and go deep. You’ll find hole-in-the-wall bars, great delis, quirky shops… exploring the non-touristy side of New York is an incredibly rewarding experience for a traveller.

With live music to be heard all across town, 24/7, 365 days a year, Music City lives up to its name. From honky-tonk bands jamming at Tootsie’s Orchid Lounge to songwriters in the round at the Bluebird Cafe and country music legends rocking the Grand Ole Opry, you never know who you might see. The creative spirit from Nashville's music landscape flows into the area's myriad art galleries, up-and-coming fashion scene, historic landmarks and chef-driven restaurants.

What happens when a "gassy" Englishman rows into town feeling thirsty? A pub is born. And from that a city—in this case Vancouver. Though the pubs are plentiful, food and drink aren’t the only things to take in during your trip. In its 150 years, Vancouver has grown into a cosmopolitan city nestled in the great outdoors. Enjoy the snow-capped mountains, waterfront forests, cityside beaches, Olympic history and the world’s highest suspension bridge. Hipsters welcome. (Don’t worry, they don’t bite.)

Is there any possible way Las Vegas could not be on our "best nightlife" list? The only way we could possibly omit it is on a technicality—since you can do pretty much anything 24/7 in Vegas, it might be wrong to call it "nightlife."

Rising from the ruins of the Aztec capital, Tenochtitlan, Mexico City offers a unique collision of contemporary city life and historic preservation. World-class museums, restaurants and parks rub shoulders with the remains of several cultures. The nightlife, the shopping and the history make it a must-see regardless of your travel style.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.
