Both sources give the same night and time, but neither confirms recent activity.
Posi's Kitchen is confirmed to exist at 1010 St Paul St, Baltimore, but its own website could not be loaded (checked Aug 13, 2026). The only dated evidence of an open mic is a ticketing site listing for 'Open Mic Night @ Posi's Kitchen,' hosted by Chef Plenty, from August 2024, over a year old and not proof of a current recurring Saturday program [s1]. An open-mic listing site is the only other source for this listing [s2].
Weekly on Mondays, 8:30 PM. The Venue's Website does not mention it.
Slainte's own website has no events or open-mic section at all, only navigation for Home, Breakfast, Lunch & Dinner, Sports, and TV Schedule (checked Aug 13, 2026) [s1]. The site appears not to list any programming rather than specifically denying an open mic, and the Monday open mic rests solely on an open-mic listing site.
A listing on badslava.com lists this night, but may not be current.
St Mary's Restaurant and Bar is confirmed to exist at 120 W 25th St, Baltimore. Other sources mention only DJ music and general nightlife programming there. No reference to a dedicated Monday open mic was found beyond an open-mic listing site (checked Aug 13, 2026) [s1].
Monthly on a Monday, 7:30 PM; no source says which week.
Call to confirm the night
A listing on badslava.com lists this night, but may not be current.
An open-mic listing site's Maryland listing names this venue for a Monday open mic (checked Aug 13, 2026) [s1]. A different open-mic listing site claims a roughly twice-monthly cadence instead, but that site could not be loaded directly, so the claim could not be confirmed. The exact street address also remains unresolved among nearby bars on the same street.
The Ivy Bookshop's own events page could not be loaded, blocked by a security check. A city tourism board's dated event page confirms 'The Hot L Poets Series continues at The Ivy Bookshop,' featuring an open mic, dated Sunday, June 14, 2026 (checked Aug 13, 2026) [s1]. The 'continues at' phrasing and the roughly two-month-old date point to an ongoing program rather than a one-off event.
The venue's events page lists this night, but may not be current.
The Manor's own events page could not be loaded, now or previously (checked Aug 13, 2026) [s1]. No source beyond an open-mic listing site pins down the day, time, or format for this listing.
The Port Comedy Club's own calendar page lists 'The Open Mic' at 9:30 PM with 9:15 PM sign-up, upcoming across many upcoming Thursdays through the rest of the year (checked Aug 13, 2026) [s1].
A listing on openmikes.org lists this night, but may not be current.
The Waterfront Hotel's own website could not be loaded (checked Aug 13, 2026). An open-mic listing site's calendar is the only source pinning a Wednesday open mic specifically [s1]. The venue is confirmed to host live music seven nights a week, which is consistent with an open-signup Wednesday event but does not confirm one distinct from its booked acts.
