It's quite expensive at 850B per head but it's worth it in my opinion. The food selection and quality is just top notch. You literally want to taste everything on display it looks so good. The dessert selection is exceptional too which comes as a surprise as most buffets are a bit lacking in that department. Be prepared for a... More

Cool atmosphere, super fresh sashimi and sushi ( of course). All the food was tasty, and the flavours did not all wash together ( like some buffets ). Top quality ingredients!!!

The sashimi - tuna and salmon alike - does have no distinguished taste. The raw grill goods are much the same, with only few sauces -... More
