Link to the Ann Arbor Go Club

The club meets in the back of Espresso Royale on State and North U. 7p-close on Thursdays and 1p-6p on Sundays. Equipment is in the crate in the back corner. Players trickle in over the course of meetings, so first-time players should come a little late to make sure they find a partner. Meetings are free, but it's polite to buy something from Espresso Royale.
