After not going to Big River for my first 3 years at BWV, we have each year for the past 3 years.
Some things that stand out:
They have an excellent selection of their own Micro Brewed Beers. Last year my DW had the sampler which was fun. Also last year I had a Cheeseburger their which was done to perfection.
This past May I tried the Beer Cheese Soup which was Great.
Also this past May Both myself and my DS had strip steaks, that were prepared nicely, other DS the Meatloaf which he raved about because it had sausage in it. My DW had (I think) Pecan Crusted Chicken. Other Apps were good too, we had a quesadilla, and Hummus dip.
Deserts were nice too.
The wait time wasn't long, and the service was very good too. On a side note last year we were also given a tour of their Mini Micro Brewery.
I say give it a shot, I can't imagine that it would disapoint you!
