The must to visit in Tallinn is Boost Juice bar (for example in Rotterman shopping centre). It's actually a chain juice bar from Australia. Bar's idea is to bring on the market an healthy version of fast food. Different kind of smoothies, shakes and drinks are available quickly (faster than a hamburger is in your hand). It's healthy, tastes good and you feel that you have made something good for yourself after having one Boost. Everything is made of fresh ingredients, though there are some "boosters" available, if you want to make your smoothie a super one. All berry bang tastes good.
