A place we like in Glasgow is St Mungo's Museum - up by the Infirmary - they have a great meeting room which works well for an audience of around 75 and the staff are very helpful.
Hope all's well
Within a gallery? art24sevenMedia at 23 South Tay Street, Dundee (right opposite the Rep Theatre) is a new venue that includes a gallery with changing exhibitions monthly. Our official launch should be happening on the last Friday in September. I also have desk space in the second office for one or two creative people (possibly graphic/interior/textile designer with use of the gallery if required). Some notice would be required as we take bookings for events by diary.
