I am from Indy and that is not a good area.
I’ve flown in and out of Indianapolis many times. I don’t know about the residential character of the surrounding area, but the Waffle House is in the middle of one of those adjacent-to-the-airport hotel and casual dining sprawl developments. It’s right in front of the Indianapolis Airport Red Roof Inn and Suites. A La Quinta Inn (Wyndham), Fairfield Inn & Suites (Marriott, and Residence Inn (Marriott) are a block away, as are several other casual dining restaurants.
12:30 a.m.? Airport overnight housing? Airport workers heading to or getting off work? Local shady types from down the street? This one could be a bit surprising.

It's surrounded by Hotels, and right across the highway from the Airport. Maybe it gets "busy" after dark.
13 yrs there myself and anyplace south of
The Indy Racetrack had a Bad Vibe.
Lyndhurst sounds familiar but all I remember is 16th and Georgetown now.

Through in the Waffle House....
