Sweets and Savories is a great option just slightly west of the DePaul 'hood and perfect for a nice bday dinner with the family. It's BYO so your uncle and dad can pick up a sixer of whatever they'd like. Food is delicious and prices are very reasonable.
I second the suggestion to print out a copy of the LTH Great Neighborhood Restaurants guide and a map of the city and just decide where you'd like to explore. There are options in every corner of Chicago and the list is as reliable as they come. You may not see some of the more touristy places you read about elsewhere, but GNR's are places worth seeking out.
One additional word of advice though--LTH is helpful not just with where to go, but with
what to order. So once you narrow down your options, have a look through some of the threads here to see what's not to be missed about a particular favorite spot. You'll be VERY glad you did

The search function is located at the bottom of the page or, sometimes, it may be easier to "google" LTHForum and the restaurant name.
Congrats on making it to DePaul (I'm an alum as well!) and hope to hear where you ended up going (and what you thought of it!!)
