McMenamins is a local "chain" of neighborhood pubs, hotels, theaters, event spaces, and of course microbreweries, often housed in historic properties.
Free wireless is available at these locations.

I've visited the Roadhouse last year and wireless was only free during happy hour. Things may have changed since then. --JasonMcArthur
