I just did this in December. I couldn't find anyone here who'd done it, so I figured I'd just try it and form my own conclusion. It was pretty good! They were running them at 1:00 and 3:00 when I was there, just show up at the time of the tour (actually a few minutes beforehand). It started with some information about the country, then he took us all around the pavillion, including into the resturaunt. Not surprisingly, there was some "see what we have to offer-don't you want to come back and eat or buy some souveniers?" But it wasn't at all heavy-handed, really a very interesting tour-and the price was right-free!
