Founded in New York's Meatpacking District in 2012 by two restaurateurs, Bagatelle has expanded to several countries including Dubai, Monte Carlo and Ibiza.

Now, the party restaurant brand has taken over the spot previously occupied by Quattro Passi in Mayfair. With a motto of 'joie de vivre', the brand is notorious for bottomless brunches and flashy clientele. The menu is largely French-inspired and includes signature dishes such as truffle-roasted chicken and homemade choux pastry gnocchi and truffle sauce.

The drinks list is just as decadent, with a range of Champagnes by the glass and light cocktails such as Monaco; a mix of beer, lemonade and grenadine. Expect glitzy interiors, from chandeliers through to velvet-covered chairs.
