Nope :)
We do suggest you close the bar when you seat for dinner. Otherwise, there will be a 10-20 minute line and it will delay bridal party introductions. Just have your bartenders explain that the bar will re-open right after introductions.
Note: The reason this happens is that at most venues the bar is closed during dinner, so people have learned to "stock up" for dinner. Once your guests hear from the bartender that the bar opens up right after bridal party introductions, they will be all set.
If you don't do this 10 minute shutdown, we have seen 30 minute delays as everyone tries to get their "just one more drink" before dinner.
