Where specifically are you looking in the cities/state @Knottie1451174793? There are literally TONS of venues that you can do this. The challenge being you don't want recommendations for Stillwater if you're over by Minnetonka or Rochester for that matter. Also, what is your relative budget and how many are on your guest list?
That said - it doesn't always save you money to bring your own caterer/liquor in. The hall we used over in Hudson for our RD and another family event was all-inclusive and FAR less than having to dinker around with having to book multiple vendors or the headaches of coordinating everyone as were several even "upper end" venues, the key is pricing everything out with what you get for the money. It doesn't save you anything if you get nickeled and dimed, always make sure you're comparing apples to apples (if one includes linen service and other charges you $5/pp make sure you're factoring that in). Having a bartender especially the way that MN laws are is to your advantage especially on the liability end. Minimums on all things bar service aren't always a bad thing!
