Any recommendations for a good authentic German restaurant in north NJ NY city area?
I would consult the users at chowhound.com a site devoted to discovery and reporting of restaurants. Pretty reliable for me. User generated, so it does take awhile to read through. Use SEARCH.
Hallo Berlin in NYC
I've heard Blaue Glans (in Tribeca) is good, and I think fairly traditional cooking. The same chef also owns a sort of modern Viennese restaurant, Wallse (in the W. Village,) where I've had two great dinners.
