Chinatown's businesses today predominantly consist of those selling lower-order, working-class goods, such as groceries, tea shops, and souvenir stores. While some businesses, such as restaurants, stand out, they are no longer the only Chinese food establishments in the city, a shift that contributed to a visible decline in foot traffic and nighttime activity in Chinatown. As the vacancy rate in Chinatown currently stands at 10%, it has been acknowledged that Chinatown needs a new approach to development, since some businesses have relocated to suburban shopping centres while others simply retired or went out of business. Examples include the closing of some restaurants and shops, sometimes in instances where the family did not have successors or where the business could not sustain itself any longer. Although there is a considerable business vacancy, Chinatown lease rates are considered the cheapest in the city, at $15–$30 per square foot—about one-tenth of the asking price on Vancouver's Downtown Robson Street, the city's upscale shopping district.
