We picked a great spot for our rehearsal dinner, the food, drinks and prices are perfect! The only "problem" is the owner's style of business is a little informal.He opened the restaurant about a 2 years ago, and he seems more than competent at running his business. They've done lots of events there before, but they don't have a catering menu or standard contract / deposit rules. I'd certainly be more comfortable with everything in writing - should I make up a contract and insist he sign it? Am I stressing over nothing?
