What would be good restaurant recommendations to watch fireworks from?
T&C, who lives in Park City, may come along with better information. But I'm familiar with PC - used to live there. I can't think of any restaurants that would have good views of the fireworks unless there's something at the resort plaza. But for me, that would be a little too close for comfort.
Seems like last year they launched the fireworks from park city ski area's base. That might block all of the views from restaurants on Main St. Restaurants at Park City ski area might be too close or not situated correctly to actually see anything either.
You could look into the rooftop patio of Boneyard and Wine Dive, as it may have the views you're looking for. I was there last 4th but came back to SLC for fireworks, so not sure if you could actually see the fireworks in PC. Seems like it might be a good spot though.
I honestly can't think of any restaurant that will offer you a reasonable view. I get what you're trying to do, but given where they shoot and what's around, just not much opportunity.
That said, two places that are worth calling to ask. First is Ruth's Chris steak house at Hotel Park City. See if they have patio seating on the golf course side that has a view to Park City. That actually might work. Other place to check is Silver Star Cafe (as seen on DDD). Their outdoor seating is on the wrong side, but you could probably just get up and walk around. Ask them.
