If you’re planning a trip to London and want to make sure you have a jolly old time, pick up Rachel Felder’s new book “Insider London” (Harper Design, $26.99).

Billed as “a curated guide to the most stylish shops, restaurants and cultural experiences” the city has to offer, the book, which is split into three parts, is packed with dozens of photos covering every district from Mayfair to Kensington.

The City Essentials section covers hotels from stalwarts (Claridge’s) to discoveries (Hazlitt’s, the former home of literary critic William Hazlitt); museums, including one devoted to Sigmund Freud; parks; public gardens; live music venues; and theaters, including Menier Chocolate Factory with its restaurant specializing in decadent desserts that sound scrumptious.

The Shops section looks at department stores (Harrod’s isn’t the only game in town), boutiques and even hair stylists (who wouldn’t be intrigued by a unisex salon called Barber Streisand?).

Finally, the Food and Drink section has a tasty collection of profiles on restaurants, gastropubs, bakeries, tea bars and the best places for fish and chips, which thankfully are no longer wrapped in newspaper to go.
