We had a great experience at Mason with the 7 course tasting menu. There is a separate vegetarian menu which we had to ask for. We brought our own wine which is possible midweek and staff managed our wine very well. The food was all wonderfully presented and excellent flavours. The cost was high as you would expect for this. The waiter was friendly and helpful and explained all the dishes very well. The only downside to this restaurant is the acoustics that mean you have to shout to be heard over the ambient noise. We will be back one day!
