Blacktail is the best bar for a date in FiDi, and while that’s kind of like being the least homesick kid at sleepaway camp, this Cuban-themed cocktail bar above Pier A Harbor House would actually be a great option no matter where it was located. It’s from the people behind The Dead Rabbit, and the cocktails (there are 40 on the menu) are similarly excellent. Order at the long bar or one of the many tables in the big, dark space, which has hanging plants and a stained glass skylight, and try some of the very good bar snacks as well. There isn’t much standing room, and the space is full most nights, so you should definitely make a reservation.
