Found this location to be one of the few stores opened during our visit on a Sunday, so popped in to have a look and to our surprise, they had a big selection of sweets and pastries on offer.
They offer some tastings at the sweets bar if you're nice enough, and my wife absolutely loved it, so now she can say she had Swiss chocolate in Switzerland. =P I personally prefer the pastries more though, and their pretzels amazingly are even better than the ones in Germany. Despite the quite expensive prices, we opted to buy a handful of the chocolates, pastries and a small souvenir here for our neighbor.
If you can look pass and can afford the high prices here, it's an excellent location to buy some snacks here, but if not, at least get the pretzels and/or 1 or 2 of your favorite Swiss chocolate here. It really is quite good.
