if you ever happen to visit bad ischl, visit this place, it's fun. the interior is still original as it used to be at kaiser's times, the waitresses wear white, laced aprons and you feel special. it's not snobby though, since there are mostly tourists. means, you are welcome even though you wear sneakers, no problem.
it's not a cheap place but I think the prices are okay. you can choose from a huge variety of cakes and pastries - not too easy, there are really elaborate creations available! the coffee is really good too!
the typical thing to get there is the "zauner stollen". it doesn't taste overwhelmingly good but it's a nice souvenir.
in summer there's a second place to sit outside, down by the river. very nice! I love to visit every time I come by!
