The Assiniboine Park Zoo in Winnipeg said the Tundra Grill and Polar Playground, which opened its doors Friday, includes a high-tech ventilation system employing pollution scrubbers and ultraviolet lights to keep the food smells from being picked up by the polar bears in the adjacent Journey to Churchill exhibit, the Canadian Broadcasting Corp. reported Friday.

Officials said garbage from the cafe is being kept refrigerated to shield the animals from odors.
