Kid-Friendly Near West Side/Little Italy—No Reservation

I am out in the suburbs, and I never get into the city, but I jealously read these posts every day. My kid has a track meet at Chicago Hope Academy on Friday, so I would like to take the opportunity to eat somewhere interesting. There will be four of us, and I won’t know what time they’re done until it’s almost over, so I can’t make a reservation. Anything within about 15 minutes that would be fun for us that won’t be a super long wait? Not seafood/sushi. Thank you!
