If you’re into wagyu beef, The Fat Cow Donburi from Fat Cow is a good one. Charcoal-grilled wagyu beef served over seasoned Japanese rice with onsen egg (and onsen egg never fails ✨). There’s also a distinct truffle oil flavour in it. We do recommend you to have it during lunch and have the lunch set (comes with chawanmushi, miso soup, and salad)
