"Bella was a fantastic host, she provided fantastic customer service, very attentive and polite. All Bar One has a positive and eclectic atmosphere. Highly recommend"

Kaylie Conroy

"My partner and I always love visiting All Bar One on our trips to Gunwharf.

The service is consistently great, the cocktails are delicious, and the food is always fresh! It’s always busy when we’re there, but the wait for food is never too long, which is a big plus.

Overall, a fantastic experience every time — we’ll definitely be returning 🍸"

Ellie Daisy

"The breakfast was pretty good, and service was timely, however I thought that the music was too loud inside for a breakfast/lunch ambience, the tables were very sticky and a great many of them still had dirty plates from the last customers laid out on them.

When I ordered, I asked to substitute out my mushroom for a hash brown and was told this was not possible.

I had the option of extra beans (or veg of some kind) so I opted for more beans. When it arrived it was barely even bigger than the regular beans. Photo for comparison with a regular beans pot inside mine. It's ridiculous that this is considered 'extra' beans.

Also after 12 noon, a member of my party ordered a coffee, only to be told that this is not served after noon. We then discovered that coffee is on the regular menu without a restriction on timings so she returned to the bar, to request the coffee once again. She was then told that the coffee machine was broken which I suspect to be a lie, as they changed their story on approaching the bar for the second time, and people had been served coffee (including me) only minutes before."
