    I have had a couple of average-bad experiences here, however on my trip on 16th March 2025, myself and my girlfriend had a wonderful experience. We had wine and some cocktails, as well as some tapas food and it was all delightful. The server, Daniel was so lovely and friendly, and made us feel so comfortable. This might have been my last time coming here, but Daniel has redeemed All Bar One for me. Up the Orient!

    Had a wonderful meal here. It wasn't very busy but that was fine. My wife has a food intolerance and the young lady who served us was extremely helpful, polite and accommodating and made us recommendations on what best to eat without that particular ingredient. She is a real asset to the place in my book! The food was lovely - the calamari had a lovely light batter and my Korean burger was really tasty. My wife had the salad with chicken and loved it too. Overall a lovely experience.

    At All Bar One Southampton, we had an amazing experience with a variety of brunch options-food and drink. The service was exceptional. Mitch, the manager, took great care of us, ensuring everything was perfect from the moment we arrived. He was all over the dietary requirements and was available throughout for food and drink service. He was all over the drinks and we’ve never had such a fantastic brunch experience. Olivia also provided outstanding support, adding to the overall excellence of the day.
