I ate at the Heidelberg in downtown Ann Arbor last Friday.
I had a spaetzle lunch special, it had a cream sauce with ham and peas, a little bit of garlic. Pretty tasty, $7 including a soda, can't beat that even going to McDonalds
If you're in the Ann Arbor area, the Heidelberg beats Metzger's (just off I-94, Zeeb Rd.)hands down in food quality, though reading some of the online reviews, I guess the elderly lady owner of The Heidelberg can have quite the attitude
