Not as hard to find as it seems. Cabs (expensive) can take you or, if you rent a car (recommended), get a map and ask directions. Everyone knows where it is. Early morning is best time to visit. Later it gets hot inside (due to furnaces) and the workers may have quit for the day. Best place to buy glassware. They will customize for a large enough order. Glasses of all sizes and shapes, plates, pitchers, specialty items. They won't haggle for only three or four items. The things you have seen in the local shops are made here. Interesting to watch workers (mostly young men) make a finished glass in about a minute. You are about ten feet from them, so the viewing is excellent.
