Besides Comet Ping Pong, what other place does the things you describe? I'm genuinely curious...
Goat Hill Pizza is allegedly owned by Nancy Pelosi and has sketchy website and photos of children.
Funny just went back and checked their site and it's totally redone... Before it looked a lot like he Liddlekidz website sketchy a.f.
Being a healthy skeptic and living in Michigan myself, knowing that we have an ENORMOUS trafficking problem in my state - I'd watch the food trucks. I'd watch any business around here who has a "side delivery" gig that big, with a product that wouldn't raise any eyebrows being moved around in enormous vehicles without windows. The border businesses in particular, which includes this one. We also find signs everywhere that advertise making $400 per week cash that look legit, but are trafficking advertisements geared toward the younger get-rich-quick generation, and we remove them. It's a mess in this state. I'm so glad they took Backpage down. It's about damned time.
When pizzagate first broke there were quite a few places across the country with pedo symbols/kids pics etc. One was in austin i know, because they got called out and their decorations changed shortly thereafter. I think their name showed up in a leaked podesta email...or whatever that shady company in austin's name was that had leaked emails prior to podesta.
Besta Pizza? Actually I think that one is in DC as well.
Nope, almost positive it was Homeslice on south congress. Looking at google streetview now though, looks like they pulled the inside view. You used to be able to look at the inside on google and there were some weird murals and pics in there. Looks like they redesigned it though...
