I have several suggestions. But regardless of where you decide to go, I strongly recommend that you be as flexible as possible with your plans, allowing for contingencies. Friday evenings are the busiest time of the week, at the airport as well as on the highways. Airport delays are quite common these days, especially in summer thunderstorm season, and an arrival late Friday afternoon is especially chancy. In addition to flight delays, you'll need to allow for additional driving time, not only to and from the restaurant, but also around the airport; for example, if you wait in the Cell Phone Lot, it can easily take 10-15 minutes just to circulate around the airport terminals at this time on a Friday, and if you park in the garage at the airport, it may take that long to wait at the cashier booth. This may make my first recommendation especially worthwhile, even if only as a backup plan in the event of a late arrival, since it involves zero time driving around the airport, and zero time driving your friend away from the airport in rush-hour traffic (and then back again).
1. O'Hare Hilton
For the first suggestion, you don't even need to leave the airport area. Last year, I was meeting a relative who had a long connection at O'Hare, for a breakfast and a lunch. All the restaurants in the terminals are located inside security, so those are not an option for a non-passenger. The passenger you're meeting will need to leave the secured area to meet you.
Where we went is the Andiamo restaurant in the O'Hare Hilton. This is the hotel right in the middle of terminals 1, 2, and 3. The person you're meeting can walk across the roadway on the baggage level, or walk below it as though he's going to the parking garage. For you, as a visitor, follow signs for "Hourly Parking" and you can park on the first floor of the parking garage in the short-term hourly parking for $4 for up to three hours. (Rates are steep if you're there longer than that - $21 for 3-4 hours - but you shouldn't be there for more than three hours once you allow time for your friend to go back through security and get to the gate well ahead of the scheduled departure time.) From the first floor of the parking garage, you just walk across the driveway into the hotel, and the restaurant is on the first floor, so you can park really close. It's a shorter walk from your car to the restaurant than at most hotel restaurants in the suburbs. And, compared with any place outside the airport, the ability to wait for your friends by sitting inside the restaurant and meeting them there, rather than having to sit in the cell phone lot and hook up via cell phone and deal with traffic around the terminal to pick them up and drop them off, is a real convenience, for you as well as for them.
As a long-time resident here, I had remembered the hotel (and the underground tunnels leading to it) from years ago as being not so great, but they've remodeled and it's nice, about what you would expect from a Hilton. For lunch, they have a contemporary "fusion" menu, American with some foreign accents. The food was good and tasty - not fine dining, but perfectly adequate, and the convenience of the location was perfect. Prices were a few bucks higher than you would find in a nice suburban hotel - which means it's not inexpensive, but not what I would consider a rip-off, either. And it's a nice dining room, a quiet, relaxing place to get together for a few hours. The service was good and nobody minded that we were there for a couple of hours. Casual attire was totally acceptable. It was perfect for my needs.

2. Black Ram
Black Ram Steakhouse is a restaurant in Des Plaines. All of the food there is delicious - the steaks, the seafood, the desserts, everything. It doesn't get a lot of press, but it gets a lot of repeat business. The proprietor greets lots of arriving guests by name. If you're looking for a great steakhouse (and seafood) restaurant that nobody ever heard of, this is it.
There are other steakhouses in the O'Hare area, including Gibson's and Morton's, but I think this is the best.

3. Giordano's
If you think your friend would like real Chicago-style pizza, go to Giordano's and order the double-crust "stuffed" pizza. Keep in mind that it takes 30-45 minutes for the pizza to bake, so you may want to consider ordering ahead.
If you prefer single-crust "pan" pizza,
Gino's East also has a location on Higgins near O'Hare.

4. Flamingo's Seafood
This one is slightly further from O'Hare, typically 10-15 minutes driving (can be much more in the Friday evening rush hour), but still not far. We have a phenomenal new restaurant specializing in Mexican seafood. As the crow flies, it's only about a mile from the northwest corner of the airport property. It's called Flamingo's Seafood and you can read more about it in
this topic.
From O'Hare you can either take the tollway (I-90 Northwest Tollway westbound and exit at Elmhurst Road, which means you're only on the tollway for a few miles) or local roads (Mannheim Road north to Algonquin Road). Then afterwards you can hop on eastbound I-90 at Arlington Heights Road and take it back to the airport.
