Diamond Head Restaurant

My fianc and I are staying at the motel next to the restaurant and decided to go there for dinner around 6:30pm. We walked in and the were 2 tables taken up, one with employees eating and another with their friends who came to visit them. We were seated and got our food. There wasn't a great selection to choose from, but we made our plates and sat down. Everything we both tried on our plates was old, tough, and luke warm at best. We waved down the waitress and told her the food was all bad and we were going somewhere else. We both had a few bites off of our plates, and she said we had to pay half price. I told her it was disgusting and I wasn't paying, she got her manager who said the same thing, I told her again I wasn't paying, she brought a man over who we explained the situation to a third time. He said "Well did you eat?" I said, yes a bite of everything on my plate and it is bad. He made a scene and told us we had to pay, after about 4 more minutes, we got tired of the whole thing and just walked out.
