The library is a private library on two floors with thousands of books (including a large collection of chess books), magazines, newspapers, and DVDs. The entire fourth floor is a chess club. Chess tables and sets abound, they have computer access and a display cabinet with a set that Capablanca used on a visit there.
I saw Yermo give a lecture at the Mechanics Institute years ago when I was visiting San Fran. I agree, it's a great club.
Anyone else?
A while back I visited a Munich chess club that met in a Bavarian pub. They had a back room reserved every Friday night. That was pretty cool.
I was a member of the Mechanics for 5 years, but I really didn't like it. The library was good, but the much older players were not as friendly to play chess or engage in chess. It may have changed since I last played there in 1991.
I liked the Palo Alto Chess Club when it was active (over 100 members), the Kolty Club, and the Dayton Chess Club in Dayton, Ohio. I liked the Tacoma Chess Club in the late 1960s and early 1970s. I have played in dozens of USO clubs that had chess, my favorites bein at U Tapao, Thailand and the one on Okinawa.
I've also been active at chess clubs in San Antonio, Los Angeles, and North Augusta, SC,
What's the best chess club you've ever been to? Where was it? What was it called? (Do you have links?) What was special about it?
I ask partly out of curiosity, and partly because my job has me doing a lot of traveling, and going to cool chess clubs in new places is a lot of fun.
