Some of the beers within different beer styles are too similar to distinguish so I'll just go with beer styles:
1. Scotch Ales (eg. Founder's Dirty Bastard & Backwoods Bastard)
2. Dunkels (mostly made by German breweries)
3. Doppelbocks (eg. Ayinger Celebrator, Troeg's Troegenator)
HM. Porters, Black Ales / Lagers, Oktoberfests
As a bonus, here's some suggestions for good beer bars / brewpubs / taprooms in Philadelphia (where I lived for 5 years until last year) and Chicago (where I live now):
Philadelphia - Monk's, Eulogy, Khyber Pass, Good Dog, The Institute, Standard Tap, South Philly Tap Room, Pub on Passyunk East, Devil's Den, Frankford Hall, Misconduct, Yard's
Chicago - Monk's (not related), Sheffield's, Kaiser Tiger, Hopleaf*, Map Room*, Fountainhead*, Beermiscuous, Revolution, Half Acre, Baderbrau, Maria's*, Howells & Hood*, Bangers & Lace*
*Haven't been yet but have only heard positive reviews.
