Hapa Sushi Grill and Sake Bar, a local Japanese-Hawaiian fusion chain, delivers a great happy hour and a fun environment at all four of its locations, but weekend nights at its Blake Street outpost offer something special: DJs. Music at a sushi restaurant? Yes — and it's not just the sake bombs making the beats sound distressingly good. More often than not, the DJs at this spot are talented enough to have you grabbing your phone to Google where they're playing next.
