I hope you are enjoying our city. if you are trying to stay downtown, Lou Mitchell’s as others have mentioned is your best bet. If you have a car and move around, Richard Walker’s Pancake house is probably the best breakfast in the area. Kaufman’s has fantastic bagels, and is a fine choice to carry some out.
And since everyone else is chiming in with evening spots, I may as well too. Greektown is probably the best dining value in the city. Located on Halsted from about 100 South to 400 south, you practically can’t go wrong. Rodity’s, Athena’s, Greek Island’s, Santorini’s, are all good.
BTW, I ate at the Weber Grill last week, and it is pretty good. Very good lamb chops, crappy ribs though.
