Edit April 2023. Ok, definitely back to 5 stars. The food was amazing with several vegan and gluten free options. Service was friendly and was a nice atmosphere. So they have sorted out the problems mentioned below and I'm happy to recommend Viet Lane.
Edit Feb 2023. Very disappointed that my booking was confirmed via email and then I got a call about a 1/2 hour later to say they have had to cancel my booking as they are full. I feel they need to improve their systems so I don't get a confirmation that they can't honour.
Previous review from 2022
Very nice food. They have a few vegan and gluten free options. The service was not great. We had to wait quite a while for drinks to arrive and then one of the mains seemed to have been forgotten and there was no check made. We had to ask for it while the rest of the group waited.
