Sometimes, it seems like all the best things in NYC happen during the workday. But since it's summer, here's hoping you can skip out of the office a bit early and head over to one of Brooklyn Brewery's Small Batch Tours, which take place every Monday-Thursday at 5pm. 

For $8, you get a small, in-depth tour of the brewery, tastings of four beers, and a glass to take home (plus way more). It jumped out at me as one of those great-deals-you-never-really-know-about, and you can find all the details and sign up over on their site: http://brooklynbrewery.com/visit/visiting-the-brooklyn-brewery
