Howard opened Michelin-starred restaurant
The Ledbury as its co-owner alongside
The Square co-owner
Nigel Platts-Martin in July 2005. The Square's former
sous chef Brett Graham was appointed head chef and later became
chef patron of The Ledbury. Despite ownership, Howard never operated
The Ledbury as much as Platts-Martin did. The Ledbury had been indefinitely closed since June 2020, citing
social distancing measures amid the ongoing
COVID-19 pandemic as impractical for the restaurant. The Ledbury reopened in January 2022. Howard also co-owns other restaurants that are less formal and "more casual" than the (now closed) Square. Kitchen W8 earned its first Michelin star in 2011 and has retained it every year since. Howard and Mascarenhas have also co-owned
Sonny's Kitchen since 2012, later reopened as Church Road in 2019. Sonny's Kitchen was originally Sonny's from 1986 to 2012 under Mascarenhas's sole ownership. On 27 September 2016, Howard and Mascarenhas opened a new London restaurant
Elystan Street, the former site of chef
Tom Aikens's
eponymous restaurant (out of Aikens's restaurants), located at 43 Elystan Street,
Chelsea. In contrast to The Square, Elystan Street is less formal and more casual. The menu is at least 25% vegetarian Howard and Mascarenhas also co-owned a London wine-focused restaurant
Gezellig from May 2019, when it opened to 31 January 2020, when it closed. The head chef of Gezellig was
Graham Long. Howard also owned and operated another restaurant Union, located at the ski resort
Montalbert of
La Plagne (France). He also owns a
chalet there for family vacations and ski trips, having purchased it for in 2006 and spending an additional for home transformation. Union opened on 16 December 2017. Martin Cuchet is Howard's business partner for Union. The Union restaurant permanently closed in April 2024. Howard launched a London-based pasta delivery service Otto on 10 May 2021. The name was changed in 2022 to Notto after a legal dispute with another business also called Otto. He opened a pasta restaurant also called Notto at the
Piccadilly road in November 2022 with co-partner Julian Dyer. ==Judging career==
