Usually I organise the Glasgow meet ups in the Concert Hall cafe. There are usually too many of us, to book a venue, as quite a few people only show an interest at the last minute and some are coming a fair distance, so the weather plays a part too.
At the last meet up, I think there were at least seventeen people.
Its a bit different from the Edinburgh meet up, where Elegran used to book a private room in a hotel, where we had a special menu.
The Concert Hall is suitable for those who come from all airts and pairts, because it is near the bus and train stations and people can purchase their food on an individual basis. Otherwise it becomes a logistical nightmare, trying to work out the bill. The cafe doesn't take bookings, so some of us come early and put coats on seats.
