Being situated directly opposite the well-known Noble Rot, this family-run restaurant will have to be on top of its game to establish itself as a Mayfair favourite.
It is not helped by its anonymity - the location, in a quiet road near Regent Street, hardly attracts passing trade, while the 55-seater dining room is comfortable yet forgettable.
The whole Patterson family is involved in the business. Dad Raymond is in the kitchen, while his wife Maria works the front of house; son Tom is restaurant manager and daughters Hannah and Lucy help out as waitresses.
Raymond was schooled in the art of traditional French cookery, yet he is a proud Scot, so many of his ingredients are sourced from north of the border.
Fish is prevalent on the menu.
For starters, I opted for the excellent foie gras ballotine with sauternes jelly while my partner went for the quail with citron ravioli and pea purée, which was a bland disappointment.
And so to the mains: my monk fish with pancetta, truffle polenta and mushroom sauce was a tasty combination, while my partner's Dover sole with lobster tortellini and champagne sauce seemed to lack a spark.
The lunch menu is a very reasonable £12 for two courses or £16 for three courses, while the à la carte evening menu is £35 for three courses.
There is nothing wrong with Patterson's - the food is good and the service is friendly and knowledgeable - but if you are looking for a memorable dining experience, you may be disappointed.
