My FH and I have an extremely tight budget for our wedding venue and catering. There is no way we can afford an open bar. Our venue is being extremely generous and working within our budget but has asked us to allow them to open their bar for 3 hours with a $500.00 minimum. We would be responsible for the difference if the minimum isn't reached. I don't like the idea of a cash bar but have no other option. Need suggestions or advice, please.
