I am sorry to hear about this.  But unless your son suffered damages from eating the food and/or the box being melted, then there would be no basis for a lawsuit and likely none to seek compensation.  Every lawsuit requires you to have damages - mainly meaning you suffered a monetary harm as a result of a wrong of another person or business.  If you son became ill  and had to seek medical treatment after he ate his food there and you think it is because of the melted box, then you may have grounds to seek compensation but I don't think this would be enough for an actual lawsuit.  In order to justify a lawsuit the damages would need to be pretty high.  So, if you are interested in attempting to seek compensation, I'd consider trying that route on your own with Ruby Tuesday.  I hope your son is doing okay.  Best of luck.
