FWIW, we were in old town Alexandria a few weeks ago and decided to try Bugsy's, which is in the old Armand's location down near the waterfront. We used to go there all the time about 20 years ago when they had the Friday/Saturday late-night buffets. The place hasn't changed a bit, though there is a new owner. I learned that Armand's never went out of business, rather the guy who owned the franchise decided to abandon the agreement and just renamed it to Bugsy's (he was a former NHL player who won a cup with the Canadians). He sold it a few years ago and retired. The pizza was still pretty good, not great, but the nostalgia factor gives it an extra star.
Bryan "Bugsy" Watson was a bit more than the run of the mill hockey player. I heard that when he retired he held the all-time record for penalty minutes in the NHL, but even if that's fake news he sure was a pest on the ice, and not afraid to mix it up.

His bar above Armand's was originally known as "The Penalty Box", appropriately so. It was THE hockey bar in the DC area for a long time. Bugsy was a warm and generous host, and really well liked in the tight Old Town restaurant community. One night my wife and I were finishing up our last beers in the Quarterdeck Lounge (upstairs bar above the Wharf restaurant) and Bugsy entered with a small entourage. We were 2 at a table for 5, and the staff asked if we could give up our table for "Mr. Watson". I kind of resented being asked and said no, but that we were happy to share the table with them. After a brief consultation the grabbed a few more chairs and joined us. I was sort of thinking maybe I'd made a mistake, but Bugsy sat next to me and was gracious in thanking us for sharing "our" table, and introduced each of his group to us. He was being fully sincere. We ordered another round, and I was chatting with him and after a while, told him (I was near drunk) that "when you played for the Red Wings, I used to "root for (the Caps') Blair Stewart to kick your ass". He laughed and said "well you know Tom, I used to give ol' Blairsy noogies just like this", at which point he put me in a gentle headlock and proceed to demonstrate the technique.
Fortunately he was only playing.
Anyway, the insider recommendation for pizza there was the spinach pie. Who would ever order that? We had a friend who insisted and after trying it that was all we ever ordered. He had to stop the Armand's recipes when he split with them but he still had a spinach pie on the menu, slightly altered if at all.
And I got noogies from one of the all time NHL's most notorious and penalized players ever, for which I am eternally grateful.
