(sorry for the double post)
What I would do If I had a day(I am totally ignoring balance here) :)
Superdawg with extra green tomatos at Superdawg
Paan on devon
go down western and get the issan sausage app. at Spoon Thai. (also get the palm cakes and jasmine tea)
Down western and visit Joe the sausage king.
Down to western and Irving park and get the hackerpeter and pan-browned spaetzle at Leschett's Inn
Go further down western and get a special venison or smoked shrimp sausage and duck fat fries at Hot Dougs.
keep trukin down western, turn right on fullerton for some time and get a cafe cubano at Reconcito Cubano. Hang out with the cuban gangsters and grandpas.
head back to toward western, but catch milwaukee and get a Bistec Double sandwich at Cafe Marianao. Hopefully you get there on a saturday around noon and hang out with 30 or so cubans and drunks yelling at each other while you wait in line for an hour. Get more cafe cubano and compare to Reconcito Cubano.
further down milwaukee and get a shake or smthg at margies candies
down western again, left on division, stop at the polish joint Podhalka between ashland and milwaukee, get some sour-pickle soup and rye bread.
from here, you could hit chinatown, get beef tendon in vinegrette from Spring World.
Cellophane noodles with ground pork at Lao Sze Chuan
get a bubble tea at joy yee's. Crawl back to hotel.
I'm a pig.
all the best, Ligament
