this place somewhat near the centre. it isn't that easy to find, but google maps will take you there.
now...if you've found it, you'll see that it looks amazing!!! the place just screams kids' heaven. it's all colorful and every element in design features some link to candy, sweets or cakes. (the bathroom sink is m&ms casted)
now for the cakes...they are divine i tell you. all shapes and tastes. very attractive and very yummy!
they also have a shop that features candy, sweets and funny gifts.
i go there every time when i'm in budapest. the longer the stay the more visits i make per stay:)
