Hi! I was an active member on this board years ago when I was planning my first wedding and now 3 years post divorce and a new fiance, I am back

My first go 'round I did the whole formal wedding thing, but this time I am planning on something much more casual. My FI and I just recently figured out our guest list and we are looking in the neighborhood of 45 adults, 4 teens and 8 kids. We are thinking afternoon reception, 4 hours max, somewhere casual. I would love to do a venue that would do the catering and alcohol, but $100/head is just way out of our budget right now. So, I'm either looking for a venue that we can rent and bring in our own stuff or maybe a smaller restaurant that would be less expensive. We are looking in PA in either Delaware, Chester or Montgomery Counties. Any suggestions would be appreciated!
