There is one new location this year that has a full bar and lets you get any mixed drink you want in the blinky cup. I'm not sure if they're just doing it wrong, so posting it here might contribute to its death, however, in the spirit of sharing: it's a little walk-up window on the far left side of Cafe La Bamba right before the start of the Vikings: Undead scarezone. There's also a great little secluded seating area back there - I've made a stop here every night so far!
EDIT to add: You get the discounted refills here too, but like previous years, you cannot get regular mixed drink refills at Finnegan's or Chez Alcatraz.
