Place ain't cheap but was totally delicious and did indeed remind me of my days in Berlin. Not to mention the staff have really thick but awesome German accents.
I am a spätzle fiend so order that as a side no matter what. If you're new to German food, just get Bockwurst (a white sausage). It's safe and good in my opinion. This will probably run you around $20 ~ not cheap by Vegas standards but this should be normal for anyone visiting from NYC, SF, or even LA.
Don't let the ghetto ambiance fool you. The food here is phenomenal! I should try coming back for lunch when the prices seem more affordable, albeit the portions might be significantly smaller.
