The closest el stop to Uno's is Grand & State on the Red Line. Uno's is located at Ohio & Wabash so you would need to walk 1 block east (toward the lake & Michigan Ave. which you would see as a street above you about 2 blocks away) and 1 block north (toward the (soon-to-be) old location of the Shriner's circus). Due's is just down 1 more block north at Ontario & Wabash, you can see it from Uno's. Hope this helps & let me know if you can make it to Chi-town again!
