Oak Barrel is a solid four stars, but I don't think it will ever get to five, because the prices are just a little too high for what you get.
I have been here at least five times now. My bf really loves it. We sat at the bar a lot, but the service is better at the tables because the bar is too big for the number of bartenders typically working. The bartenders are really nice but they just can't keep up when the bar is full.
Some highlights from the menu are the beef burger and barbecue amish chicken pizza. I was skeptical of a pizza with peanuts on it, but it is awesome. Skip the fish and chips as there isn't enough fish. They have a lot of good beers on tap. The atmosphere is nice. A good place to eat before or after your movie next door.
Definitely worth trying out!
