My girlfriend and I have been to Murphy's probably 4 times; each time we try something different, and each time we love what we get.
The atmosphere is great on Friday/Saturday nights, and on certain nights they have a band play German polka music, which adds to the experience.
The food, although relatively expensive, is priced well considering how much you get and how good it tastes. The beer is quite expensive, but you can try some pretty unique German beers, so for some it may be worth it.
The schnitzel (any meat), potato pancakes and Black Forest cake are a personal favorite.
I always recommend Haus Murphy's to people looking for good food, and especially for those looking to try something a little different.
