Taking the prices posted in the above link:
There are 181 items (54 food, 17 dessert, 40 wine, 39 beer) on the Marketplace menus this year. If you bought 1 of everything, it would cost $861.90.
Last year, if you bought one of everything at each of the booths, the cost was $715. (2009 was $819, 2008 was $728). The numbers only included the smaller beers (if there was a choice).
Out of the above numbers:
2008 / 2009 / 2010 / 2011
food: $201.65 / $245.50 / $219.95 / $226.55
dessert: $52.00 / $49.25 / $46.45 / $44.90
wine: $221.00 / $199.50 / $152.60 / $139.95
beer: $140.00 / $173.25 / $125.70 / $227.5
The jump in beer cost is mostly due to having only one size to buy this year (according to the web site). For the previous years, the costs were based on the smaller sizes.
