You've supped on some schnitzel. You've gobbled down the goulash. You've pigged out on a pierogi or two. It's Saturday night at Amber Restaurant and Gallery. Now your server places a small glass of a ruby-red liquid in front of you. "But I didn't order this," you say. "It's on the house," she says with a mysterious smile. The drink is called Nalewka Babuni, Poland's leading dessert wine. The only decision you have is whether to sip the cherry-flavored drink slowly, or to sling it down. Either way, this is a surprisingly tasty way to end a meal. The folks at Amber pour this digestif only on weekend evenings. It's Polish! It's cherry! It's free! What more do you want?
