The Asian dishes here are absolutely delicious, full of flavor and clearly made with care. The service was outstanding — staff were friendly, attentive, and made us feel very welcome. Overall, it was a wonderful dining experience and we will definitely be coming back.
I was thoroughly impressed with my meal at Cosmo. There was so much variety and it was nice to try little bits from the different cuisines. The food was very high quality which was amazing given the amount of different options. Desserts were also super tasty and was again impressed with the amount of choice. Would of been nice to have some strawberries for the chocolate fountain however there is plenty of other things to have. Overall had a great time will definitely recommend to others and will definitely be returning, thanks
This restaurant is an absolute gem that deserves all the praise! From the moment I walked in, the warm and cozy ambiance instantly put me at ease—super inviting for any occasion. The staff were incredibly friendly and attentive, going out of their way to ensure a smooth dining experience without being intrusive. The food was nothing short of exceptional: the signature main dish was crispy on the outside and juicy on the inside, with perfectly balanced seasonings that highlighted the freshness of the ingredients. The side dishes were light and refreshing, complementing the main course beautifully, and even the drinks were a delight—visually appealing with a bright, tangy flavor that cut through the richness perfectly. What’s more, the value for money is unbeatable. Whether you’re catching up with friends or dining alone, this spot hits all the right notes. I’ve already recommended it to everyone I know and can’t wait to come back for round two!
I recently dined at this restaurant and had an exceptional experience. The atmosphere was warm and inviting, with a comfortable and stylish interior that made the evening feel special. The staff were attentive, friendly, and knowledgeable about the menu, offering helpful recommendations and ensuring every detail was taken care of. The food was outstanding – each dish was beautifully presented and full of flavour. I especially loved how fresh the ingredients tasted, and the portions were generous without being overwhelming.
Great value for the money and a very well run establishment. A huge variety of food to suit anyone's tastes. The staff were all really friendly and attentive and the drinks were all reasonably priced. A nice atmosphere and I would definitely go there again when in the area.
COSMO is one of the best open buffet in town. There is a huge diversity of world food and cuisine to select from. From Carvery, deli to asian food. There is something for everyone. The desserts’ section is my favourite. Highlighted and surrounding the chocolate fountain makes it very attractive but the taste is even better. There is ice cream mini-section and popcorn. There is also a fruit section. I think pictures would tell a better story!
Huge amount of vegan meal on my plate made me pleased and would like to return again. Loved the coziness of the place too. Spent nice time there. I hope they keep their plant based (e.g. aubergine) and vegan meals (e.g. tofu).
Nice decor. Clean enough including toilets (usually it’s hard to keep clean for very busy places like this). Large variety of food. Quality is great, better than average all you can eat buffet. Service attentive. Great for families.
Went here on my birthday with my Miss! Food is not bad but not sure the cleanliness as no one wearing mask or plastic gloves as strictly as previous reviews mentioned. Just beware of the chocolate fountain as I saw a kid taking the marshmallow directly from the fountain. Not sure how long the restaurant would change the chocolate… Anyway £15-16 per person on weekday night that can have buffet dinner is fair. And It’s really nice place to have once a half year or a year with your family and friends.
Absolutely love Cosmo. It's one of the most popular restaurants in Southampton so it's a clever idea to book if you want to avoid disappointment in being turned away. Staff are absolutely lovely. Never had bad meal here. Thank you so much Cosmo
