Until Edinburgh finally catches up with New York and gets itself a table tennis bar, I will continue to make do with pool. Sadly, these days I am out of practice. Since Mai Thai down at Holyrood shut down, I can count on the fingers of one hand the number of times I’ve troubled a baize. The odd visit to Diane’s Pool Hall was as much as I’d done until a visit to the recently re-opened Marco’s on Grove Street.
