About Bellevue

Learn more about the host city, Bellevue.

Bellevue is the largest city on the east side of Lake Washington, across from Seattle in Washington state. Bellevue is perhaps the most ritzy part of the Seattle metro area and the Puget Sound region, mainly due to the presence of Microsoft at nearby Redmond and other tech companies occupying the downtown office towers. The dense downtown has much of the region's upscale and luxury retail. It also has many neighborhoods comprised of large houses, and excellent vistas of the water for the lucky few. It is considered more pleasant and safe, if blander, than Seattle, though the influx of international tech workers has led to a vibrant Chinese community.
