Maybe I was there at a bad time, or my standards are too high, but I didn't like the Big River Grille at all when we went this past July. I had their sampler, and I have to admit I was pretty disappointed.
My problem was mostly just that the beer was very bland. Their biggest beer was a red ale at 5.4%. None were what anyone here would qualify as "hoppy". Of the 6 beers they had, I think 3 were light lagers (Southern Flyer? Gadzooks?), one was a wheat (Wowzer's Wheat), one was the (Rocket Red) red ale and the last, I never found out what it was, since the bartender couldn't remember, and it had no name on the tap handle(!).
The worst part was their wheat beer - it smelled like hot garbage. Literally. I wish I knew a better descriptor than that, but that's really what it reminded me of - a dumpster full of garbage on a hot day. I don't know what the problem was, maybe dirty lines, maybe fermentation temperature issues, but it tasted AWFUL.
