We have visited Portland on two occasions and this really is an exceptional restaurant. The menu is beautifully designed with three options for each course, plus a selection of "snacks". The cooking is hugely inventive to create delicious meals that are beautifully presented. The cocktails are nothing short of genius. The atmosphere is professional but relaxed, and the décor impeccable. The restaurant is very competitively priced, given the quality of the cooking - this is surely one of the best value restaurants for fine dining in London.
