I'll be in Graz for a few days in the spring/early summer, and I've seen people recommend Zotter in a few threads. The only trouble is that we'll be there without a car, and the Zotter website's suggestion for how to get there from Graz is quite a faff: it's a train from Graz to Feldbach (just over an hour), then a very infrequent bus from Feldbach to Zotter.
What I'd like to know is: is the Zotter Chocolate Experience such an incredible thing to see that it's absolutely worth the trek? Or is it only worth bothering with if you can drive there? Has anyone else on the forum done it by public transport; can you weigh in on how you found it?
Any tips or advice very welcome.
