Wedding welcome party spot

Hey y'all! I am getting married at the end of May, and my fiancé and I are searching for a spot we can have a casual "stop by, have a drink if you want, and say hi" welcome event the day before especially since a good percentage of our guests will be coming in from out of town. We are relatively new to MKE. We imagine that at any point there could be as low as 25 people to as much as 70 - 80 people coming through. Somewhere spacious is are biggest priority, and ideally in or near third ward. Some spots we have thought of are Juneau Beer Garden, amped, and up down. We are open to any suggestions!
