This is fun. If you buy something at a Fifth Avenue merchant through Feb. 14, you get a free raffle ticket to win a spending spree of up to $1,000 on the Slope’s best shopping strip. That sounds like a mighty fine way to spend an afternoon, maybe even two. Participating places include a whole bunch of shops, restaurants and bars we really like, with the noteworthy absence of Bierkraft. Here’s the list of Fifth Ave. venues where you can pick up a ticket, and All About Fifth has the details on the giveaway.
