University of Illinois at Chicago prof Lynn C. Hattendorf Westney has a paper titled Dew Drop Inn and Lettuce Entertain You: Onomastic Sobriquets in the Food and Beverage Industry–basically, it’s about funny restaurant and bar names. There’s a short discussion of names, categories they fall into, etc, but mostly it’s a list of names of restaurants, bars, and inns from around the country, many from Chicago (h/t Serious Eats).
