It's looking like we are coming down in favour of the 3rd - so that's one variable off the list.
Now for venue: Bobsmum - would you be able to get to Edinburgh? I think the rest of us are flexible enought to go to either Edinburgh or Glasgow, except Harrysmum, who has expressed a preference for East Coast - but I am not sure about mears and Tissy (I realise that Mears would also need to negotiate a shift change).
So, next question: if it's the 3rd, who can make it and do you have a preference for Edinburgh or Glasgow (or no preference)? Also, do you want/need to bring kids along (and what age would they be)? That can then help in working out a venue.
Let's assume a lunchtime do.
I'd prefer Glasgow (if only because it was in Edinburgh last time) - but am happy to go across to Edinburgh. I'll probably NOT bring ds (although I still need to check with dh if the date is OK and whether he is doing anything else) - but it's not a big deal if I do have to bring him.
If it is Edinburgh, I would suggest Agenda again - it was good food, relatively easily accessible (for West Coasters - train to Haymarket and bus along Corstorphine Road), plus it had a good wee soft play area for the kids.
Despite the fact that I'm Glasgwegian, I haven't been able to think of any "kid friendly" venues" in central Glasgow - the best I could come up with was downstairs in Princes Square (Buzzy Wares or d'Arcy's) where the kids can then run around the mosaic area.
Anyway - back to the floor for comments!
