Chicago vs Rio de Janeiro

Chicago is the American city that gave the world the skyscraper, and it still shows off its skyline better than almost anywhere. Glide along the Chicago River on an architecture cruise as guides decode Art Deco towers, glassy modern giants and the movable bridges overhead. Stroll Millennium Park to see your reflection bend in Cloud Gate, then follow the Riverwalk past cafes, kayakers and wine bars tucked below street level. Dinner means deep-dish pizza, a buttery, cheese-loaded pie that takes about 40 minutes to bake and is worth every one, though locals will also steer you toward tavern-style thin crust and an Italian beef. Evenings belong to Lake Michigan: ride a bike along the Lakefront Trail and watch the towers catch the last light at sunset. The L trains make it easy to roam without a car, from Loop landmarks to neighborhoods like Wicker Park and Lakeview. Stay longer and add the Art Institute's world-class collection, Navy Pier, a game at Wrigley Field, the lakeside Museum Campus and the free Lincoln Park Zoo. Summer brings festivals and patio season; winter brings serious cold, but also holiday markets and cozy blues clubs.

Rio's setting is unmatched — granite peaks rise directly from the city between Copacabana and Ipanema's beaches, with the Christ the Redeemer statue watching over it all from Corcovado mountain. Samba, Carnival, and a beach-centred daily culture define the city's rhythm, alongside favela communities that are an essential, complicated part of Rio's social fabric.
