We ate lunch - it is on the main road in Manteo just after entering Manteo and has a lunch buffet sign for $3.99. The lunch buffet is a budget buffet and has General Tso's chicken, Sesame Chicke,n and Triple delight along with egg rolls, crab wontons, donuts, fruit, jello, rice, and a couple of other dishes. It is all you can eat and lots of local people eat there, indicating that the food is safe.
A drink is $1.19 and the food and drinks are self-serve and all-you-can-eat and drink on/in the styrofoam plates/cups.
