While the décor is quaint and traditional, adding a certain degree of charm to the place, the service, quality of food and price lets it down massively. During a group visit, we found the staff pushy and they did that old trick of adding extra portions onto your order, even though we didn't ask for them, nor dis we have room to eat them. Due to the overall unfriendliness of the staff, we decided not to leave the full 12.5% service charge that had been added to the bill. It clearly stated on the bill that it was ‘optional’, so we left probably around 7% of the total bill. On leaving, one of the waitresses bullied one of our group, who unfortunately was unaware that the service charge was stated as optional, into coughing up the rest of the 12.5% service charge. This soured the whole evening for us, more so than the very average, and yet over-priced, tasting food. I had bratwurst from the specialities menu. It was a large sausage, which tasted okay, in onion gravy – dull. I am aware that this is possibly the only Swiss restaurant in London with fondue on the menu, and it appears that they may be relying too much on this, leaving very little time for good customer service and value for money.
