What can I do if a customer won't pay for catering?

Question Details: I own and operate a pizza catering company. I booked a wedding and sent a contract for the wedding to the customer. On the contract it stated that I would bring enough to make 80 pizzas. After talking to the customer a month or 2 before the wedding she told me to bring 115 pizzas just in case since she wanted to be sure everyone was fed. Then a couple weeks later the customer told me to bring even more. The day of the event came and I ended up making 130 pizzas. After billing the customer they will not pay for anything over 80 because that was all I was contracted to bring. I have none of the past correspondents in writing about bringing extra but did make note of it on the contact when we spoke. I have myself, my wife, and an employee that were all there at the event making the pizza and know for a fact we made that much pizza. Would I have a case for small claims court or is this just something I have to eat and learn a lesson from. I have been in business for 5 years and have done 100s of events and never been accused of anything like this. Is this a decent case to take to small claims court?
