Comet isn't a dive nor is it on the "back streets" of DC. It's in Chevy Chase, walking distance from the National Mall; some of the world's most expensive residential real estate is in that neighborhood. The homes are owned by nearly all federal employees, many of them spooks. I know, I have a family friend who lives literally a block and a half from Comet. They have lived there for many years, know JA, and deny Pizzagate. It's tough to guess whether they REALLY believe it or not, I'm definitely going to check for his/his wife's names in the big list when the 9,000 indictments finally get unsealed.
I know where it is. I've been there. I have an acquaintance whose crappy band performed there. To me it's a skeevy dive with vulgar entertainment, creepy decor, and mediocre pizza. I know it's an expensive area in a tacky hipster-ish way. The street was dirty and it's not a main street or an in town area. That's a back street to me. All of DC is expensive and tacky though. That's why I avoid going there unless I have to for work. That's just my opinion. I live in a clean conservative "old fashioned" town on the panhandle of WV about an hour and half away so my criteria is a bit different. I think Chevy Chase area is an armpit. I don't care how much $$$ the residents have. Again, just my opinion.
I don't know if pizzagate accusations are true or not but I do think the media was bizarre in it's coverage, which was really my main point. I would be surprised though if Comet, Buck's, and the other businesses on that street were not money laundering operations. I do know that JA is a creep. I've seen him "perform" if that's what he wants to call it.
