Max's is a great German restaurant. I've been a semi-regular patron for over 20 years and have never been disappointed.
The portions are huge--entrees come with your choice of two sides. I always get the potato pancakes and the spatzle. The pancakes come with a side of chunky applesauce (it tastes homemade and not overly sweet) as well as sour cream. The spatzle comes with gravy (I believe it is pork gravy) and are always perfectly cooked. Other sides that are good is the German-style potato salad and the slaw (v. tangy in a vinegar sauce).
Their saurbraten is good and my friend swears by the rabbit dishes, but I almost always get the sausage sampler. The sausages are always fresh, perfectly cooked and Max's carries a nice spicy/brown mustard that's a perfect accompaniment.
I have yet to get dessert there, because I obviously cannot exercise any control and gooble up everything on my plate (an assortment of breads and rolls also come with the dinner, and the apple butter is very good). However, they do have a nice selection of desserts, ranging from cake to strudel.
Their non-German options are also very good: vegetarian sandwich and omelettes are good and available for lunch.
And they're usually in the Entertainment/Enjoy book-great to save some jingle money. Even without a discount, for the quality and quantity of food, it's an excellent value.
