IT's pretty loud given that it's almost always full and they have that open kitchen. The # of kids there also contributes. I should say that once the fireworks are over the place does quiet down a lot. And I also should say the noise level isn't bad enough to actually ruin a meal. We eat there our first night every trip (and will be there again on May 1).
And about the 'Wine Room"-it is away from the main area and the open kitchen, but it is NOT adults only or always kid free. The last time we had dinner in there there was a table of about 20 people, about half of whom seemed to be kids. They were very loud---
