Today, I had lunch at Akiyoshi. I had 90 mins. Suki buffet. Very full until the evening and don't need dinner at all.
Akiyoshi offers both A La Carte and Buffet. For the buffet I took, it's 494Baht(Net) per person, that's about $16.
This is a very good grade of beef compared to other restaurants.
Akiyoshi also provides free dessert for those who choose to have a buffet.
For Thai people, if you are going to Akiyoshi for the buffet. I'd recommend buying the member card in LINE Gift Shop, it cost only 50Baht instead of 100Baht and you can use the discount privileges right away. So if you're going for 2 people buffet, that would give you discount around 80-90 baht which worth the membership price since first time use.
