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.
The venue's events page suggests it may have ended.
Weekly on Thursdays, 7:00 PM. The Venue's Website does not mention it.
The venue's own entertainment page (checked Aug 31, 2026) advertises curated live music every Wednesday through Saturday -- jazz, modern, and country acts -- and never uses the words 'open mic' or 'comedy' anywhere [s1]. Thursday programming reads as booked entertainment rather than an open-signup mic.
Weekly on Fridays, 5:00 PM. Something about this has changed recently — confirm before going.
The venue's own events page, checked Aug 31, 2026, lists several dated 'Open Mic Music' Fridays in 2026 (Apr 3, 10, 17, and May 1), all confirmed to be real Fridays [s1]. This directly contradicts what was listed before: a Monday 6:30 PM mic that had rested only on an open-mic listing site. The day and time are now Friday, 5:00 PM, per the venue's own calendar.
The venue's events page suggests it may have ended.
Weekly on Thursdays, 7:00 PM. The Venue's Website does not mention it.
The venue's dedicated events page (checked Aug 31, 2026) never uses the word 'mic' anywhere on the page [s1]. This page is more complete than the homepage, which only showed an ambiguous, undated Thursday slot. Combined with the venue's karaoke and sports-bar branding, no evidence supports an open-mic format here.
