Eastlake Ave, Belltown

Eastlake, true to its name, runs along the east side of Lake Union between the University Bridge and Downtown, connecting into Union St at its southern terminus. This means it also runs pretty much directly under or right next to I-5. There are a few apartments and condos built along the street, but it's too noisy for most people.

On the up side, it's packed with interesting places to eat, shop (esp. REI's flagship store!) and a few clubs to party at.

More than that, it's a fantastic alternative route into Downtown, especially if the freeway is jammed up (as it often is during rush hour).
