I ate at Wienerschnitzel last Sunday, the third time I've been to one. I got the beef chili cheese dog with onions, the same thing I've gotten all three times; it was decent, but the one bad thing was that I really had to pee and there was no bathroom.
The second Wienerschnitzel I'd been to had a little bathroom outside in the back, but that one was in Canoga Park, and this one was closer to downtown LA (it feels like the number of places with public bathrooms goes further and further down as you get nearer to the downtown of a city).
I ended up walking a few more blocks and then peeing at a gas station. Then I went to a bar, got there just before last call, and had a tonic water.
