Packed lunch sounds good to me tbh (I know that skint feeling, I'm scrounging money from Dh to come as I miscalculated my money this month!)
They have little barns to eat in, anyone who still wants to buy something can get it from the cafe and join us outside!
If anyone does want to meet later than 12.30, CAT me and I'll email you my mobile number, and we can let you know were we are!
