I was admitted into a ph.d. program at Northwestern and am going to Evanston for the official visit day in a couple of weeks. My dad is coming out to Chicago to spend a couple of days with me, too.
I'm looking for places that are casual, moderately priced (entrees <$20), not too adventurous or "ethnic" (my dad's a picky eater), and preferably someplace where lower-sodium options are available. The best options are seafood or steak (if reasonably priced), Italian, burgers, and brewpub/new American-type places.
My dad would be just as happy at a chain, but I'm seriously considering spending the next five years of my life as a student out there, so I'd prefer to get a feel for the town. So, closer to Northwestern is better, but if there's something good elsewhere in north Chicagoland, that's fair game.
