Yes, I had to try it. Happened to be at the AYC for Wendy's birthday, so I horrified her friends by ordering the bacon-infused vodka martini garnished with a pickled quail egg. The vodka didn't taste particularly bacony, just very smoky like Lapsang Souchong tea or liquid smoke flavoring. I liked the tangy quail egg, it made a perfectly good olive substitute.
The verdict? Not disgusting, just very smoky-tasting. B- for overall taste, A for novelty value.
