So someone, somewhere, somehow heard my oft-plea "but there are no sweet treats at the carts!
Don't get me wrong, I think the carts are great, I just usually pack my lunch (cheaper and healthier!). Mid-afternoon, I sometimes want a snack, but I don't want vending machines. Now, there's a cupcake truck! They keep people up to date on when they're coming out and what they have that day on Food-Driven: The Cupcake Truck Blog.
Sadly, it's up on the Hill, and I'm down at the Med School, so it will be more of an occasional treat than a regular one, but that's probably what cupcakes ought to be. I had the chocolate cupcake with cream cheese icing. The icing was spectacular - it was very real cream cheese frosting, not the over-sugared variety, with that lovely tarty finish. I can see this being a regular "treat for trekking all the way to Science Hill for something" event.
