Kinda a silly question.. how are you serving water?

I would have waitstaff with pitchers, personally. It's less likely to get spilled and there will be more available for people who might go through a lot of water at dinner.

Our venue is providing all of our drinks, but I believe the servers are filling the glasses initially and then leaving pitchers. We're still so far out that we haven't had the formal discussion about service with our venue's catering team.

I actually do not know LOL i am pretty sure the waiters had pitchers. but for my venue they already had alcohol and soft drinks at each table

We are having a taco station so our guests will be going up and grabbing their food (sort of like a buffest style, but someone will be serving their food). We are going to have servers go around with pitchers and serve our guests - just so guests have one less thing to worry about/get up for.

But really, I don't think there's a right or wrong way to do it.
