I don't know what can top this.
I went to a small bar in Lincoln Park with a friend of mine this evening. It was doing absolutely no business, which should have been warning enough. But it'd gotten decent reviews and we picked it anyways.
I ordered a Sazerac (which was on the menu). When the bartender asked me if I would prefer it up or on the rocks, I should have suspected I was in for it. At any rate, from what I could observe, here's what this particular cocktail consisted of:
3 oz Maker's Mark (bourbon, not rye, but I'm not here to be persnickety.)
3 dashes Peychaud's bitters (okay, so far, we're okay)
1.5 oz Vya sweet vermouth (wait, I said Sazerac, not manhattan)
1 oz Lucid absinthe (dear god, man the escape pods!)
After the bartender spilled half of this abomination transferring it from the tin to a martini glass ("sorry man, party foul"), he then set it aflame.
It was the first drink I've ever sent back.
