I thoroughly enjoyed my visit to Happy Cakes while on vacation in Vienna, so much to the point that I went a second time, even though I was only there a few days! The staff are SO friendly (I met the mother and daughter who own Happy Cakes, and both were so pleasant). They were happy to serve me while seated, and we had a nice chat. Make sure to take a look at the cookies and cakes before sitting down, so you have an idea of what to choose. The cakes were AMAZING -- they don't "taste vegan" at all, and that's more proof a vegan diet can be just as fun and delicious (but cruelty-free) as compared to a non-vegan diet. Happy Cakes is a must visit for anyone in Vienna! I ordered a soy melange coffee, a lemon cake with maple glaze, a toffuti tart, and two cupcakes (raspberry cupcake and a peanut butter cupcake), both topped with vegan whipped cream/frosting.
