Venue only

Having those aspects planned first makes the venue more difficult since many places want to do the catering both to charge more and also for insurance or practical reasons. Are you looking with a small budget or a specific guest count as priorities? Do you need indoor sites or maybe patio or barn venues?

You can check for community/park facilities that may allow you to plan your own food options. Make sure that the entertainment will not be an issue.

Venue is typically the first thing that you schedule so like Pat mentioned you might be more limited in options since you already have these things planned especially if you already have a set date/time with these other vendors.
