What's everyone's experience with consumption bars (full bar) as far as the final cost goes? Obviously cost differs between venue, drink price, and the type of guests. I'm just trying to get a general idea of an end cost. We're having about 150 guests. We're also wanting to do an Italian Soda bar for those under 21. Basically I'm deciding if I want to do just open beer and wine, with hard drinks available to purchase, or if it won't be too much of a difference, doing a full open bar. I just am trying to avoid a surprise $10k tab by the end of the night.
