The pitch at Cosmo is simple and it does not pretend otherwise: one price, a plate, and more than 150 dishes laid out across the room to return to as often as you like. It is the kind of place that settles an argument at the table — the person who wants a curry, the one who wants sushi, and the child who will only eat chips can all leave happy from the same bill. On a wet afternoon in the town centre, or with a group that cannot agree, that counts for a lot.
The food
The buffet is arranged by region rather than by course. There are sections for Chinese, Indian, Italian, Japanese, British, Greek and French cooking, along with a salad bar and a long run of desserts. Two stations are cooked in front of you: a teppanyaki grill turning out prawns, salmon and steak, and a carvery with roast beef, turkey or lamb. Pudding is where it tips into theatre — a gelato counter, a chocolate fountain, cheesecake and tiramisu among the trays. This is buffet quality, even and generous rather than remarkable, which is the fair trade for the range and the refills.
The setting
Inside it is large, bright and built for volume rather than intimacy. Tables turn quickly and the room hums, so it suits a family lunch or a casual catch-up better than a quiet dinner for two. Soft drinks come with free refills, and there is a bar if you want a cocktail with the meal. Baby changing and step-free access make it manageable with a pushchair.
Where it is
Cosmo sits in St Peter’s Quarter, just off Old Christchurch Road, in the middle of the town centre. The Square, the Lower Gardens and the main shopping streets are all a few minutes away on foot, and the beach is a downhill walk from there. If you are staying centrally it is an easy walk out and back. You can see how it lines up with the rest of the area on our map of Bournemouth.
Good to know
Prices are fixed per person, with lunch charged at less than dinner and a lower rate again for children — check the current rates before you go, as they move around. It is worth booking at weekends and in the school holidays, when the town-centre restaurants fill up; walk-ins are taken when there is room.
