I've driven by it 10 times a week for the last several years. I didn't know what it was at first, either.
You're a half mile south of Andersonville, where there's lots of stuff (on Clark around Foster and continuing north), but the immediate area near Lawrence is actually kind of sparse. Spacca Napoli would be an excellent choice and, indeed, probably the closest thing that isn't Byron's Hot Dogs or Golden Nugget. Get off your Lawrence bus when you go under the train tracks at Ravenswood (near a Golden Nugget), walk south on the east side of the tracks on Ravenswood, Spacca Napoli is 3 blocks south at Sunnyside. When you're done, walk east to Ashland, north to the theater.
