To get your fill of company lore and the low-down on Brooklyn Brewery's craftsmanship (they brew six types of beer), head to this New York City borough on a Saturday or Sunday to go on one of their tours. If you don't want a guided experience, visitors can also hang out at the brewery and enjoy the drinks (beers are $4) on both days as well as on Friday nights. Snacks are offered but you can also opt to order in your own munchies. Admission: Free.
