Banquet halls for reception in Vienna

Your most significant cost is going to be food/beverages for your guests (around 50 - 60%), so that's where I will center my thoughts for you (Flowers, Linens, Band/DJ/Photography, etc. typically make up the other 40% of your budget). The pricing below is what we tend to see in planning for our clients in the US.

If you'll be serving a catered dinner you should estimate around $50 - $80 per person for food. So you're looking at a range of $7,500 - $16,000.

If you're going to provide an open bar, then you should estimate around $5 - $8 per drink, per person. If each person has 4 drinks during the event you're at around $3,000 - $6,400.

Your best bet is to start by prioritizing your guest list, as the number of people who attend has a very direct impact to your total cost for the wedding.
