If I would compare all ice-cream stores around Vienna, Bortolotti would be the Number 1. The ice cream is so delicious and you can get over 30 different flavors. This store is also the original one. The other stores opend afterwards based on their success.
The only sad thing about it, that they increase the price every year IMHO.
But for the taste still 5 Points!!
Great restaurant at the summer time, where you sit on a platform on the river. Great an big ribs. Reservations should be done as soon as possible for the platform!!
