Based on the information provided, we know that at the wedding there were only two types of drinks served: beer and wine. We also know that a total of 320 people attended the wedding.

Out of those 320 attendees, 200 people chose to drink wine. We don't know how many people chose to drink beer, but we can figure it out by subtracting the number of wine drinkers from the total number of attendees:

320 - 200 = 120

So, we can conclude that 120 people at the wedding chose to drink beer.
