In the lobby of the hotel [1] is a store by the name of “Market Orlando.” I can only describe it as if hippies-cum-yuppies from Berkeley [2] ran 7-Eleven [3]. Gluten-free, organic, farm-fresh snacks, chips, salads and sandwiches.
Oh, and cruelty-free pizzas. Can't forget those.
It has an extensive wine selection (Napa Valley present!), but the soda selection is pretty much limited to Pepsi and Diet Pepsi (which sucks because I'm a Coca-cola [4] person myself). There's also about a bazillion brands of artisanal water.
Oddly enough, I did not see any granola for sale.
I'm telling you, Orlando [5] is weird! When it's not trying to kill you.
