I third the Shulte and Herr recommendation. The food hearty and satisfying,goes well with a Belgian beer. I also find the entire staff kind and interested in their patrons. Its worth my trip from Boston!
...and I had a great dinner there last night with my son. I had the sauerbraten and he had a terrific ravioli type dish (I forget its German name). Potato pancake app. Every table in the place brought their own bottle.
