Poor food, rude service - pricy...what are we paying for? Ambience?

I always find the food decent here until last week when my husband and I went there for dinner. Not only was the waitress very rude, but the ravioli my husband and our friend ordered tasted spoiled or like it has gone bad. It has some tomato sauce in it. We did tell the waitress it tasted weird but she made a nasty remark saying it's not like it's some canned food.

My husband went home and had stomach ache and mild diarrhea. We called back the restaurant to complain. The manager said he will go in the kitchen to check and call us back. He never did. We called back after three hours and he just said there's nothing wrong and never even bothered to apologize. My husband has not eaten the whole day except for cereal in the morning. We were there at 3:30pm for early dinner/late lunch. Suffice to say, we'll never go back there again.
