Today Biwa is celebrating 5 years! Apparently they are celebrating all week with specials on the menu, and owner Gabe Rosen is going to make sure that the much mentioned Biwa burger will be available all night tonight. Friday’s special is a Biwa style mabo dofu, and according to Eater PDX 10% of all proceeds will be donated to Spring for Zenger which is a non profit educational farm. P.S. if you like sake, this is a spot for you!
