This is always a little worrying when the owner is eating front of house in a chefs hat !
We booked and as the web page said we took a bottle of good wine.
We waited for 5 minutes at the entrance as the owner/ chef looked at us but did not get up from her table.
Eventually she went into the kitchen and a lovely young lady showed us to our table.
We were then told we could not byo.
That was ok and we perused the menu and wine list.
The owner / chef became quite agitated and rude and made comments about us to her friends.
We decided we would be better spending our money elsewhere!
There is no ambience and the attitude does not lend itself to a good culinary experience.
Looking at other reviews from people who went one step,furthur and actually ate there I would give Bahn Thai a big miss !!
