I had a great meal here last year. However, disappointment last Monday, a shock. My wife's Braised Beef and potatoes were salty, almost inedible. My own duck was tough and fatty. Both plates were covered with an unsavory brown sauce, reminiscent of unpleasant restaurants - in Peru. Even the service: while my wife was just starting her salad (which was also late), the waitress tried to shove her own brown sauce plate at her. We've found out it's not worth complaining, just avoiding. They usually get snarky and resent even a polite comment, then nuke your original plate and dump it back at you.
For great German food: Zum Schneider's in NY. It's a beer hall and you can barely get in
most nights, but the staff (in all the chaos) is more considerate and the meals superior to Black Forrest!
