For those who don't want to scroll through a slideshow, here is a paraphrase of the list and my thoughts regarding the same:
1. Too many ingredientsAgree with this one in part. I like to have drinks I have some chance to replicate (or at least approximate) at home. And I feel I have had some real failures where there is just too much going on. But, if everything works together, I am not categorically opposed to drinks with a large number of components. I do think that most drinks could/should probably be made with 5 or fewer components.
2. Too expensive (>$15 drinks)Not sure what prices are throughout Chicago these days, but with the exception of the Aviary (which I have not been to) and maybe some hotel bars and the like, I would guess that drink pricing does not yet exceed $15. I would have to feel like I was getting something else in return for the price (a great view, unique atmosphere, etc.) to go $15 or above -- but most places that have that something "extra" typically don't have the best vision or execution (because they don't have to), so I steer clear. The good thing about the explosion of cocktail bars in Chicago and expansion to "lower rent" neighborhoods is that it seems you can get well made cocktails at a lower price point.
3. Flavored vodkasMany serious cocktail bars largely eschew vodka, so can't say I have seen this. Would not be surprised if hotel bars, restaurants, and even non-cocktail-focused neighborhood places are expanding their offerings to try to capitalize on the cocktail craze, and would not be surprised if what passes for a specialty cocktail in some of these places utilizes trendy flavors of vodka.
4. Molecular cocktailsAgain, have not seen this and really don't much see the point. As noted above, I like to have drinks I can try to replicate/approximate at home, and would probably skip any "molecular" cocktails with liquid nitrogen and the like if I came across them on a menu.
5. Cutesy or small serving vessels (tea cups, mason jars)Have not really seen a lot of this -- many places serve cocktails in cocktail glasses, champagne coupes, or rocks glasses. I think I did have a punch once at Barrelhouse Flat that was served in a tea cup; it did not bother me. This one is possibly more ubiquitous at those places looking to capitalize on the cocktail trend and put their own spin on it (or use glassware on hand without revamping that).
6. Herbal and floral infusionsFloral not really to my taste, but herbal can work (particularly when done through herbal liquors or bitters with a stronger herbal component).
7. Bacon in drinksHave not seen this in many (any?) serious cocktail bars; seems more like a gimmick. Have not had a burning desire to try any bacon-infused anything I've ever come across.
8. Retro drinksClassics are classic for a reason, and most have stood the test of time. Sometimes I have a classic cocktail and say to myself, "No wonder that one seems to have gone out of circulation for a while," but most work. Classics are also good for places that maybe do not have the best cocktail "program," particularly if you don't mind being moderately obnoxious and telling the bartender how you would like it specifically.
9. Metal strawsHave not seen this anywhere. Not sure I can recall the last time I got a drink with a straw (which I tend to take out in any event).
10. Cocktail snobberyAgreed that things can be a bit obnoxious, on both sides of the bar. That said, if a particular approach is taken and explained in an appropriate manner, I have no issue with bars and patrons wanting to hold to a higher standard -- just don't be condescending about it.
