Let's say I've got this friend who can't drink coffee or alcohol anymore due to deleterious physical effects though he may be able to drink both again in the future. Let's also say that this friend is on the dating circuit and trying to avoid the awkwardness of inviting someone to meet him at a bar and only ordering a soda water with a lime wedge. Does anybody have suggestions for a coffee shop/bar alternative that has ambiance suitable for a first/blind date? Like a tea house or something. Or perhaps a recommendation on a classy non-alcoholic cocktail? On the East side, preferably, and not necessarily a place to get a meal in case it doesn't go well.
