He has replied. You can take a packed lunch but no alcohol. He didn't mention non alcoholic drinks so they may be okay if the seal is still in tact. Saying that to avoid carrying weight, and having no hassle, I'd be tempted to take food only in and just buy drinks when you are in there. It might be £2 for a bottle of pop but you wont be drinking gallons of it so take that one on the chin.Ask him if you take food/drink in with you please. Can't find anything on the website and have tweeted them but had no reply. Cheers.
