This may be old news:
We dined at Polka at Verdugo and York last night and were surprised to learn that the original owners had "retired" and moved back to Poland (last year) and their cousin had taken over the restaurant, according to our waitress, who assured us that the recipes and the cooks remained the same. The dining room got a minor remodel, losing much of the clutter, though the Guy Fieri poster still greets you at the door.
Wife had the goulash and I had the pork cutlet and we shared some pierogis. I couldn't discern a loss in quality, though we aren't exactly frequent diners. The biggest change: It wasn't packed like it always has been whenever we dine there. Maybe the regulars know something we don't and/or may be able to comment about any lowering of standards.
