Good atmosphere, and attentive staff. We didn’t book a table and had to wait at the bar, but it was no longer than 20 minutes. The cocktails were quite pricey, however the pizza was tasty and large in size. It did go cold quickly, but luckily was given a takeaway box to bring home. Would recommend and go again.

I went to L’Osteria Southampton with friends and we had such a lovely experience! The service was friendly and attentive, and the wait for our food wasn’t too long at all. The pizzas were huge, delicious, and definitely worth the money. I also really appreciate how they take the time to reply to each and every review—it shows they genuinely care about their customers. A fantastic place I’d happily visit again!

The food was absolutely delicious and beautifully presented. We were served by a very kind and cheerful lady who gave us great recommendations and patiently answered all our questions. The restaurant has a great atmosphere – you can see the kitchen at work and the dishes being prepared. The only downside is the noise, but it didn’t disturb our conversation.
