Now, let's get straight to the point. Why do you wanna for this buffet lunch:
First and foremost, unlike most of the Japanese buffet restaurants, you don't take food from the counter. You order from the menu. Yes, they have ala carte menu for the buffet
The food is fresh, and freshness is the key when you are having sashimi
The place is nice, cozy. Unlike others which are quite noisy
You can request for a room if you want, then you can do "your things privately"
The price is reasonable: RM 55++ for adult, RM 28++ for children. As compare with RM 88++ from other restaurants (you know where I'm saying). Of course Rakuzen doesn't offer Häagen-Dazs ice cream
Of course, given such a good deal, you need to make your reservation in advance. When I said in advance, it means at least a week before.
