Public Square Coffee House — Variety Open Mic

A page on tockify.com suggests it may have ended.

A San Diego open-mic calendar site (re-checked Aug 31, 2026) does not mention 'La Mesa' or 'Public Square' anywhere on its current listing [s1]. This calendar is also known not to cover La Mesa generally. A previously cited detail page for this event could not be reproduced. The only remaining basis is an open-mic listing site's claim of a weekly Wednesday 7:00 PM event with no listed type.
