Once upon a time Brooklyn was full of breweries, then they left, and in the 90s the Brooklyn Brewery emerged. You can visit for happy hour on Friday night or during Saturday day, and on Saturday there are free afternoon tours on the hour, ending with free samples. To get beer, you buy tokens from the cashier near the entrance, then get on line. (It's a good idea to tip the beer bartender.) Once I was with a group and we wanted to go on the tour, but it had been canceled--so they gave us each two free tokens! It's a great way to sample the variety of beers. Just make sure you don't take the beer outside--you could get busted.
