When we ate a WPE in September, we could get an entree, dessert and a drink (fountain drink, not a bottle drink out of the cooler). I got a pizza, my husband got a roast beef sandwich with some great chips, and my son got a pasta dish. They told us we could choose between 3 desserts, a packaged chocolate chip cookie, a packaged brownie or a nice little creme brulee. We all got a creme brulee, which was quite good, so I can't tell you what the cookie or brownie were like. (if we would have had to dash off, we might have got them, since they were wrapped to go).
I don't remember if there were any exclusions on the entrees now, everything we wanted was on the Dining Plan, so we were happy campers.
Hope this helps!
