We easily found street parking at a meter. You can use a credit card at the meters (or change), print a receipt and put it on your car dashboard. Our parking was $2 an hour for a maximum of 3 hours, but meters are only required until 10pm.
The weather was Warm evening. I wore shorts and a tshirt. It was very warm in the theater. It's a very small venue, and the seats are packed close together. Be prepared to snuggle up to the person next to you, and for it to be very warm inside. .
