Looks sunbaked and shuttered. Perhaps it was soundproofed to help the tenants who woke a hangover near an airport.
Allgauer's is still a name in Chicagoland dining, but I can't find anything on the Fabulous Think Twins. If that's what the sign says. I suspect they were a brother / mentalist act that really did have mutant powers, but never got their lives together and lived in boozy contempt for the Normals.
They liked it here. It was cool and dark.
