All you can eat World Buffet Restaurant in Southampton

Out of an abundance of caution and concern for the health and well-being of the community, we have taken the decision to temporarily close COSMO Southampton until further notice. We have had no confirmed cases amongst our staff but to ensure no spread in our restaurants, COSMO Southampton will be temporarily closed. Apologies for any inconvenience caused to any bookings made for this period – the health and wellbeing of all our staff and customers is our priority and we will still continue to monitor the situation closely and follow all Government guidelines stringently. Thank you for your continued support and we look forward to welcoming you back soon.

Are you in the mood for an oriental buffet At COSMO there are so many delicious dishes that it can be difficult to make up your mind about which one to eat. That’s why we provide tiny versions of our full size meals at the Tasting Kitchen for those who want to sample a variety of different cuisines. From Thai and Indian, Chinese and Japanese, the Tasting Kitchen is also an ideal way to encourage kids to sample different exotic foods.

Enjoy all of the flavours of the Continent

Taste Italian classics such as spaghetti and meatballs and pizza at COSMO Southampton. We stone bake all our pizzas in wood fired ovens to give it that authentic Neapolitan smoky flavour. Our pizzas are delicious enough to eat on their own, but you can also enjoy them with garlic bread and one of our crisp and delicious salads with a range of dressings.

For those who love continental food, our selection of cheeses and charcuterie is the perfect way to round off a meal – or as a meal in itself. Sample their delectable flavours along with olives and dip pieces of freshly baked bread in olive oil and vinegar for a truly Mediterranean experience.  

Located in the newly built extension of Westquay Shopping Centre above countless bars and shops, COSMO Southampton is the perfect place to stop by after a day of retail therapy, or to refuel during a shopping trip. Pay us a visit for lunch or dinner, whenever suits you.

We offer a slightly reduced menu during lunch services, so if you’d like the widest possible array of world buffet foods, we recommend dining with us for a culinary experience that you won’t forget.
