I visited Teuscher for a chocolate event. Its a shop-in-shop under William Ashley. We tried Champagne Truffles which is their specialty. Their chocolates are made in small batches and made with minimal ingredients. The staff was courteous and very knowledgeable about chocolates and history of the brand than just focusing on selling you more chocolates.
While the Champagne Truffle was for $3.50 each, we all deserve a treat once a while :)
