This is what it says on their website -
" While gentlemen are welcome to wear a jacket and tie they are not required to. We would ask that no trainers, open toed shoes, sportswear or short sleeve shirts are worn. "
Personally I consider eating at Wiltons to be an "event" I would not want to be seen with a man who would not wear a jacket and tie, if only out of respect for his partner . In my experience, ladies always dress nicely to eat out in a restaurant of this calibre.
Enjoy this very special Restaurant.
Just smart dress. No tie required but jacket would be a good idea. You will know why when you go
I think it is expected but I rocked up after a day out in jeans and t shirt - not really big into dressing up and did get a few sideways glances
Shirt yes, tie not I would say. Smart casual although some people may feel flip flops are within this description.
Not a tie but this is not the place you walk in very informal.
I think a jacket is always appropriate at Wiltons, but I usually don't wear a tie at lunch. I do at dinner. Of course you're likely to see no jackets, but most men will wear them.
No. However you will enjoy it more if you dress with a jacket and shirt (no tie needed) as it fits the style and ambience of the place. It is how people dress which contributes to and respects what it is: a venerable old institution.
