Eastlake is named because of its location on the eastern shore of Lake Union.

Eastlake is bounded on the west by Lake Union; on the north by Portage Bay, beyond which is the University District.

The neighborhood contains a mixture of residential buildings, both houses and apartments, and small businesses, especially on Eastlake Avenue. Though populated by all manner of Seattleites, Eastlake is a particularly attractive location for people with ties to the University of Washington, which can be reached quickly by a number of bus routes. The neighborhood is also home to, several Seattle institutions including, Julia's 14 Carrot Cafe, The Lake Union Dry Dock Company, Louisa's Bakery and Cafe, Serafina, the original Red Robin gourmet burger restaurant, numerous houseboats, and the annual Eastlake Shake fair (renamed Lake Fest in 2006). The fair features live music, local vendors, and--a neighborhood favorite--the Eastlake Shake Pet Parade.
