Zum Schneider is a Bavarian bar and restaurant on Avenue C and Seventh Street, and if you like bars, especially of the German variety, this place is for you.
When I have been there, I have found, and enjoyed, opportunities to speak German with the staff.
Feel free to arrive hungry. There is a full menu with offerings like Sauerbraten, Wiener mit Brot, and Grießnockerlsuppe (this last one is Bavarian-style matzo ball soup).
