A few years ago we attended a wedding reception in a nice quiet park in St. Paul. It was in a neighborhood and it had a nice building with beautiful views of the park, a kitchen and a dance floor. I think it could be used for a ceremony also. I can't remember the name of it, but I sent a message to the bride. If she gets back to me I'll revise this response to send you the name.
It is the Thompson County Park in West St. Paul in Dakota County. You can get information about it from the Dakota County Parks website. The building is the "Dakota Lodge" and it is either nearby or overlooking Thompson Lake. It was a very nice setting. Good luck and congratulations.
