Third Floor Espresso have very cleverly decided to divide their menu into two parts: a "drinking menu" and a "tasting menu":
"Some customers want to hear all about the coffee and really experience something. They’re there to taste and want to leave having enjoyed their coffee and hopefully learned something. We love these customers.
Other customers just want a cup of coffee. They’re aware that we’re quite into what we do but they dont want to hear any shpeel, they just want a tasty cup of coffee. We love these customers."
Whether you want a quick classic cup or to savor a €7 Esmeralda, I'd strongly recommend Third Floor Espresso (3fe).
