The expensive pineapple spears sold in the cart on Main Street (by the Market House) are SO delicious and juicy that I would probably pay twice what they cost for one of them (though I would not be happy about it). Plus, they are a good size as well - not a wimpy little sprig that poses as a spear. I cannot stress enough how refreshing these spears are on a hot day. Now, of course, they happen to be sitting, happily embedded in ice, right next to the hideously priced juice bottles, but ignore the $4.00 juice bottles and grab a spear. You will not be disappointed. Fruit is one thing that DLR tends to do very well, whether it be at the carts or in the restaurants. The fruit I have had at DLR - melon, berries, pineapple - is among some of the freshest and tastiest I have had.
Now, on the junky side of things....I do love a good, messy, ooey gooey, generously-sized cinnamon roll, and that hunger can be fulfilled at Blue Ribbon Bakery. That and a blended mocha and I am good to go!
This is sort of a snack/sort of a beverage, but we just tried this great, slushy concoction called a Tropicool, which is sold at Rita's in DCA. The strawberry Tropicool was yummy. Absolutely delightful on warm day (if you just cannot make it over to where the much healthier pineapple spears are located

)
During holiday time, I am in love with the hefty gingerbread-men-with-mouse-ears cookies. So good. I also tried the shortbread Christmas tree and Snowmen cookies, but those gingerbread men with ears are soft, chewy and substantial.
For a sort of dessert/snack idea, at Carnation Cafe they serve the ample Matterhorn Sundae as well as a scrumptious piece of apple pie a la mode, which, in addition to vanilla ice cream, also comes with lots of whipped cream and strawberries.
For a nice protein snack, Bengal BBQ in Adventureland sells chicken, beef or veggie skewers.
Heck, now I have made myself hungry!
