Hakuzou Japanese Restaurant is still open for business. Mainly doing take away and delivery orders (which I believe have a 10% discount as well these days). But I do think you can go there for a sit down meal, though not sure if that is still happening or if government rules have stopped that. I'll be ordering some delivery this weekend for the family. Their beef teriyaki and beef steaks are excellent. And I love their potato salad, fried shrimp dishes and fried chicken steaks, etc. It's not all sushi and sashimi. As a matter of fact they have loads of 'non' raw fish dishes. (By the way, someone asked if they had another restaurant in Buriram in this thread - no, but they have opened another restaurant in Roi Et.)
If you want your favorite restaurants to still be there once this Covid virus stuff is over try to help them stay alive and able to re-open once the virus scare is done by getting some delivery foods on occasion from these places. Either by using Food Panda or Surin Delivery and the other delivery type places, or the shop's own free delivery services. I am afraid many of these places closed now will not be able to re-open due the the virus shutdown. The finances just will not be there the longer this lasts and the longer they lose custom and income.
