The address is incorrect. Though bearing their sign, the actual restaurant is further ahead by the dock. They also have a branch in down town. Hence no need to visit their head quarter.
If you want something cheap and good, go to (Feng) Sashimi. If you are willing to pay more for even better stuff, Soonyi is the place to be.
Their misoshiru broth is a must order. NT$20 per person. All you can drink. There is tuna chunks in the broth. I guess this is their way not wasting their left over sashimi.
