I checked out The Duce on a Friday evening for a Woodstock event. I took an Uber so I can't comment on the parking situation.
Ambiance (5/5): This is one of the things that I liked most about this sprawling bar and restaurant. As you walk in, you'll see a retro bus that you can go in, and outdoor bar, and a rooftop (with its own bar as well). Which is a fun place to hang out when the weather cooperates. I spent most of my time indoors on this visit. The interior has several bars, stages, and plenty of seating. This includes picnic table-style seating, bar stool seating, and a few comfortable couches. I loved the aesthetic, overall. Even though I was there for a special event, I would definitely come on a regular night, too.
Service (4/5): I ordered from the same bar the entire night. Friendly and efficient service. My only pet peeve? They don't give you an itemized receipt, nor do they give you a customer receipt, unless you ask. I hate when bars do this.
Food (N/A): While they do have several food areas, including dessert, I had dinner prior. Next time around.
Drinks (4/5): The Duce specializes in cocktails served in mason jars with fresh fruit and garnishes. They have a large menu with cocktails broken down by spirits including vodka, gin, rum, tequila, and whiskey. I tried three different cocktails and they were all delicious. Their most popular one is the strawberry limeade (vodka based). Think of a spiked drink from Sonic and that is what it tasted like (I may have done that back in the day ;)). The drinks aren't cheap but they're well-made.
The Woodstock Summer of Love event was an awesome time which I would put on your list if they do it again. Regardless, I would return any day of the week, special event or not.
