Quote crashmon="crashmon"I'm guessing the answer is no, as this is a football ground, but can you take a flask?  We used to take a flask to Ealing.  If they have MyPie will be trying them, but generally we usually take a flask'"
The rules for football are quite strict as you know.  I'd love a beer at my seat; which we do for the Ladies matches.  However, you SHOULD be okay.  This is what AFC Wimbledon publish on both their individual and general Match Day Guides:
Fans are permitted to bring water in a clear plastic bottle if they wish. However, no glass, cans, or metal bottles will be allowed. Thermos flasks are permitted.

I doubt MyPie will be there, although there is a chance as with the football the day before it's more likely they will do the "double".  Tried their guest pie a few weeks ago.  Steak, Cheese and Jalapenos.  Wasn't convinced it would work, but loved it.  I often start to lose interest in food after a few times, but I'm still a fan.  By default you get plenty of gravy (which is very tasty).  They don't skimp on the quantity.
