We can knock back a few margaritas on pretty much any day of the week, so were surprised that it was only the fifth-most-popular cocktail in our just-released Mixology Survey. Surely it should crack the top three! Well, maybe people are drinking the same old blend of lime, triple sec and tequila. We went searching in River North for some unique spins on the classic libation - from a jalapeno infused ditty to one stuffed with pineapple pulp. If you are in the mood for a cocktail crawl (and if you think the marg should be numero uno in next year's survey) check our our selections below.
