City overview
Seattle is the Puget Sound city where Elliott Bay, Lake Washington, the Ship Canal, and the Olympic and Cascade mountain views frame a compact but steep urban core. Pike Place Market, Capitol Hill, Fremont, Ballard, Belltown, the International District, and Seattle Center give the city its mix of seafood, coffee, music, tech, ferries, and long gray-season weather.
Food & drink
Seattle food is seafood, coffee, and immigrant counter culture: salmon is grilled or smoked, Dungeness crab and oysters come from cold Pacific waters, chowder lands in market bowls, and teriyaki shops turn grilled chicken with sweet soy sauce into a city staple. Pike Place Market, Ballard seafood rooms, the International District, Capitol Hill restaurants, and the Fremont-Ballard brewery belt add pho, sourdough, seasonal berries, roasters, and taprooms.

City overview
Vancouver is a Pacific harbor city squeezed between Burrard Inlet, English Bay, the Fraser River, and the North Shore mountains, with glass towers, beaches, rainforest, and ferries all close together. Downtown, Gastown, Yaletown, Kitsilano, Granville Island, and the West End each give a different version of the same city: water views, mountain weather, and food shaped by the Pacific Rim.
Food & drink
Vancouver food is Pacific Rim and coastal: sushi, salmon, spot prawns, dim sum, ramen, Japadog hot dogs, butter chicken, poutine, and Nanaimo bars all fit the city. Granville Island Public Market, Richmond night-market trips, Robson Street ramen, Commercial Drive cafes, and Chinatown bakeries are the first route.
