Very nice. Always good to see businesses willing to open their doors to chess.
Hate to put my “but” in, but… I would think McDonalds would be the last place I’d want to play chess in. Noise level aside, I could see my pieces and board becoming grease-victims. (Even a cheap set and vinyl…) But that’s me.
And if it were chess at Mickey D’s or no OTB chess… Praise the Pawn and pass the Big Mac, please. 
Well the McDonald’s we played at here in Raleigh wasn’t too bad 95% of the time. Occasionally we’d get the after basketball game crowd or a big family coming home from church on Wednesday night (right as we hit time pressure). And once there as a potty mouthed thirteen year old chewing out her boyfriend on the phone for 15 minutes. Beside better that than nothing. I am glad we have a quieter place now.
In Massachusetts the late Gus Gosselin originated a series of scholastic tournaments at Burger Kings, later on also holding tournaments at Papa Ginos. Gus’s son Matt is now running the tournaments now that Gus is gone. I helped at a few tournaments when my nephew was playing. These are essentially entry level tournaments for low- to mid- rated players, mostly in elementary school.
It works best when there’s a part of the restaurant that the tournament can more or less take over. Obviously this has to be arranged in advance with the restaurant management. As I understand it there was no rent but it was expected that a lot of players and parents would eat at the restaurant. Every now and then a restaurant patron would insist on eating at one of the tables in the chess area and we’d just have to move board numbers around to work around that table. Usually the tournaments have been held on Sundays when business is normally slow at the restaurants.
When I was working in the area I grew up in, about 70 miles where I live now, I started a chess club on Thursday evenings (I spent the night at my mother’s). I wanted the complete club experience to be either free of charge or a very minimum amount spent.
I found a local Burger King that had a nice lobby area where we could play. They were happy to have us there for free and they would turn off the music for us and everything. What was nice about that place is it was very easy access and they were opened until 11:00 pm so we could play later.
There were times that were noisy. Usually though, by 7:45 the crowd died off and we had the place to ourselves.
Seeing that I was just starting the club, the players were all novices except for 2 of us. We never had long time control games there, and I wouldn’t want to have a G/75 or even G/60 in that environ. After a little over a year, we found a quieter and still free spot.
The video showed these guys playing on the standard, USCF solid plastic sets and boards with noticeably no clocks. So it appears they are playing quite casually there.
