I think the food is great and the 2.5 hours allowance is generous enough for the price. There were variety of food available. The grilled salmon was my favorite. One thing I like is that they provided mineral water instead of juices only. The ice cream were bomb! My friends and I all liked it very much!!

Great food with fresh seafood. Ice cream was great! Only that you can't sit together if you go in large group.
