Kewpie Corporation is inviting Londoners to discover how one simple squeeze can transform one of the world’s most iconic sandwiches. Through a new experiential pop-up in Covent Garden Piazza, the iconic Japanese mayonnaise brand is bringing its rich, creamy, umami flavour to the heart of London’s food scene, celebrating the ingredient that elevates the Tamago Sando AKA the iconic Japanese Egg Sandwich.
Visitors to the Covent Garden pop-up can explore a Kewpie Konbini (a Japanese convenience store-inspired experience), taste the Kewpie mayonnaise Tamago Sando, pick up a limited edition ‘Kewpie It’ Mayozine and have a chance to win free merchandise.
Venue: Covent Garden Piazza, London
