This Central District poke bar was too popular to remain in just one location, so it added a Broadway outpost in the spring just a mile north. And it’s added something else, too: Besides saucy, fresh tuna and salmon, the Hawaiian shop now serves Dole Whip. Cup Bap makes the swirly substance in-house year-round, offering toppings like li hing mui (salty-sweet dried plum powder) and pineapple chunks.
