I actually managed to not embarass myself in a Polish restaurant this time, although the waiter probably figured I had made a mistake when all I ordered was an entre - a pork fillet stuffed with fruit - schabe z owocom and tea. Unfortunately, I only had 70,000 zloty with me - that's about $4 US at current exchange rates - and so I had to limit myself.
It was really good, though - the kind of food I've been looking for in Poland! And it didn't hurt to not overeat at my late meal (it was 9:00 by the time I finished). I even left an extra 10,000 zloty with the bill just because I was so pleased to have survived in a restaurant by myself.
