The best place to drink beer is obviously at a brewery. The ales and lagers are far fresher than at your local bar, and if you fall in love with a new IPA, for example, someone on site can tell you all about the malt and hops that provide its flavor. Washington's brewing scene is more crowded than ever, and an increasing number of breweries are acting like bars, offering happy hours and events to lure more patrons into their taprooms. Check out these 10 brewery and brewpub happy hours and you won't have to pay full price for your beer all week.
