Is it food poisoning?

My family and I went for dinner at Billy G monte….my gosh I never got so sick when I got home. I was ****tingand vomitting the whole day. almost . I am in bed as I right my review can’t do anything , I’m weak. I just hope the food was fresh because there’s no way I was that sick. Also where you take the left over to cos I believe the only explanation we experienced this was cos of the food was not fresh. We had a very very bad experience and I’m definitely not going back there.
