Odd, I quite like Barq's. While it's not as good as the likes of Stewart's and such, I'd put it above Mug and A&W in a second. Barq's Red Cream Soda is tops, though.
I almost never drink soda anymore, though. I had some at the movies the other night, and that was probably my first in months.
And birch beer is awesome. Pennsylvania Dutch all the way.
