Medlar’s menu is imaginative without causing puzzlement: foie gras ballotine salad with hazelnuts, tuna tartare with harissa, red-wine braised octopus. Take your parents, beg the manager for a green banquette cubby section at the back, make Dad bring his credit card, order him a large glass of Pinot Noir and an under-blade fillet with bone marrow and béarnaise. This may be the first non-disappointing thing you’ve done in their eyes for decades.Every dish appears perfectly executed, seasoned and portion-controlled to leave you jonesing for your next course. My starter of crab raviolo with samphire, brown shrimp, leeks and bisque sauce was so blissfully good I could have licked the bowl and worn it as a hat until my guinea fowl arrived. This was also a plate of hap-piness: perfect potato gnocchi, Jerusalem artichoke, a delicate sauce of Reblochon.
