The agency has been hired by 1 Lombard Street and French eatery Papillon.
Both restaurants have charged Redleaf with managing corporate and media relations activity.
Michelin-starred 1 Lombard Street was launched 10 years ago by chef patron Herbert Berger. South Kensington-based Papillon was created by Danish-born restaurateur Soren Jessen and head chef David Duverger serves up the French cuisine.
Both accounts are being led by Redleaf creative director Ian Haworth and account director of media campaigns Rachel Argyle.
