I have been reading mixed feelings about Karakers being closed. I think it is great that they are being checked along with all restaurants everywhere.
Food poisoning is something no one needs to experience. I have had it a few times, but nothing like the case I had from a restaurant last July. My stomach has not been the same since..... you can also have just one bad clam, mussel, etc, which is something the restaurant may not be aware of. So be happy your plans were changed temporally!
