While this was embarrassing and annoying, contract damages are based on monetary loss. If you had had to pay more to cover, the difference would have been recoverable damages. Since you didn’t, I don’t see where you could recover. Next time try for a liquidated damages clause. Such a clause agrees that damages would be difficult to measure in the event of a breach, and in effect gives the plaintiff a penalty, although you can’t call it that.

I agree that the measure of your damages would be the difference in price between the caterer you originally contracted with and the replacement contractor, if any. Hopefully, you got your deposits back. If you incurred other monetary damages as a result of the caterer's breach, you could include that in your demand and suit - for example only - if you had to pay an additional $1,000 on a tent rental because the event was delayed, etc.
