And my husband corrected me... he would have wanted Springton Manor (https://springtonmanorfarm.com/); which is a County of Chester property, but they have a contract with a catering/event company. So if you go there, you are stuck with their catering and there are some other choices that they restrict (DJs, Bands, etc).

But they definitely have options for if it rains - they have both indoor and outdoor facilities.
