This place looks like a luxurious restaurant but you should not have come here without knowing about this place. It is considered to be an abandoned restaurant but if rumors are to be believed some gangsters come to dine here secretly. They have set up an automatic locking system at the door and that is why the door got locked as soon as you entered the restaurant. It does not look like there is anybody inside to help you and even if there was someone inside you would only get yourself in more trouble. I think you should hurry up and try to find a way to escape from this restaurant.
