We admit it: sometimes we skip out on a Friday-night flick because, after a crazy week, all we're craving is a cold brew. No longer. The Somerville Theatre (55 Davis Square, Somerville, 617.625.5700) is now serving beer and wine along with the obligatory buttered popcorn and Raisinets. Choose from three Harpoon beers - IPA, UFO, and a rotating third selection - for $4 apiece (pretty much comparable to a concession-stand soda these days), and red or white wine for $6. Sure, it's served in a plastic cup - no glass allowed in the theater - but we'll endure it for such a sweet deal. The only downside? You can only buy one drink at a time, so you might need multiple trips for refills. But hey, the sober guy next to you can always fill you in on what you missed.
