Vine Street Pub, order them Tim's Style, they are fried then grilled.. baller as fuck. cash only though.
if you're of age Pub on Penn on Wednesday nights has 5$ all you can eat wings and 7$ pitchers.. hit me up if you go, usually there for a couple hours.
as far as italian goes ^^, Shells and Sauce is great over in Congress Park, as is Osteria Marco on Larimer Square.
Pizza by the slice - Benny Blancos or, Pizza whole, Protos.
And you absolutely MUST eat at Tom's Home Cookin'. Its near Cervantes. They make a few dishes every day and close as soon as they run out, around 2pm or so. Always wonderful.
