Went through 2F with a rather-long layover last year. Within the 1st demi-heure in the lounge (morning, granted) a whole case of Champagne - supposedly a good label (i.e., not Kirkland) - was freshly uncorked for self-serve. Wife and I each took a sip and decided it wasn't for us. Given the proximity and the quantities of the stuff stashed away within 100-200 Km of Roissy, I wouldn't be worried about any shortages.

Get to spend a few hours in 2E in a few weeks.
