Is it cheap? And I mean not like 10 dollars a person. More like 6 or 5

I believe it's around 8. Children are cheaper depending on age. Tues kids eat free.

The buffet is $9 per person, I believe. But it's worth it.

Depends on whether you get a drink or water. If you go after lunch they have a 7.99 deal

Try and find a coupon. It will help.

With your drinks 2 adults are a little over $20
