Went on a weekend lunch, not very crowded. Service staff was efficient, used QR code to scan when we want to top up food for the buffet, so we didn't have to keep asking for the waiter.

Ate Australian wagyu, good flavour. Not as flavourful as Japanese wagyu on my opinion, but it's still good beef! Anyway, the difference is really not huge and u can save about $15 per pax if u take Aussie I think?
