About COSMO
COSMO is a restaurant chain in the United Kingdom, founded in 2003 and headquartered in Barnet, that brings the energy and range of international five-star hotel dining to the high street. Its all-you-can-eat buffets, found across the UK and Ireland, are built around live cooking: teppanyaki chefs grill fresh steaks and seafood in front of guests while hundreds of other dishes sit ready nearby. Families, couples, food enthusiasts and large groups all dine there.
The food travels widely. Pan-Asian cooking sits alongside authentic Chinese favourites, and the dessert station keeps bite-sized homemade cakes, creamy chocolate pots, fresh fruit, rich ice cream and puddings. Everything is prepared fresh, and the lively, friendly atmosphere is part of the appeal.
World buffet restaurants of this kind let diners move between cuisines and take as much or as little as they like in a single sitting, which suits mixed groups and fussy eaters. Bills can be settled with Visa, Mastercard or PayPal, and the company posts news on Facebook and Instagram.

Questions About COSMO Vouchers
Why might my COSMO voucher not work?
A code fails when the order misses one of its conditions, such as eligible products or a minimum spend, or when the promotion has ended. Each offer's details list its conditions.

Do COSMO vouchers need a minimum spend?
No offer on this page mentions a minimum spend.
Is there a COSMO rewards program?
Yes, COSMO runs a loyalty card programme that varies from one location to another. Diners collect stamps or rewards, though the exact terms differ by branch, so it is worth checking the local branch's offers page.
