My mum and I had a lovely meal in here on Christmas Eve. It's in a beautiful old building, huge high ceilings and yet still felt warm and cosy. All three courses were very nicely cooked, were fresh and had great flavour. The service was also very good and we thought it was good value.
The only reason I haven't given 5 out of 5 is because we ate at another restaurant the following night that was evening better, and slightly cheaper. Overall though we enjoyed Peppersack very much and were very impressed by the quality of restaurants in Tallinn on our Christmas trip.
