Hi, Richard,
Thanks for the pointer. Turns out that they meet there every night (!), even on Sundays. I went this evening (Friday), and there were probably five boards going. This is, apparently, their busiest night. Very nice group, very sociable and welcoming, and they accommodated my less-than-passable French. I leave early Sunday morning, so this was probably my one time this trip to play there. I'm happy I did.
I also played a blitz tournament another night at another club--Observatoire--who meet Wedesdays (I think) at a cafe near the Glaciere metro stop.
Great fun for a guy from little Victoria, Canada.
I'll miss the British Open. Sigh.
Cheers.
Seymour
