Bow ties are cool if you are one of the rare breed that wear them. I only know 2 guys that do and they both, surprisingly, look stylish rather than stupid.
As to dress code, are you using a time machine to visit restaurants from long ago when people could be bothered giving you shit about whether you wore a jacket or tie? If so try 1971, I had a lot of fun that year. And had to wear a jacket and tie a couple of times.
This. Unless the OP are going to jump into the TARDIS on a man date to some stuffy French restaurant in the early 80s, you don’t need a jacket and tie.
Remember that The Doctor also thinks fezzes are cool.
I was under the impression the really fancy places still had a dress code. Especially the restaurants inside the very fancy hotels. Like The London in NYC or some of the places in Washington DC.
Even if it isn’t enforced at the door. I wouldn’t want to be the only guy in a polo shirt if everyone else is in coats and ties.
I have eaten in a three star restaurant last week in NYC - jacket required - no jeans. I was meeting three friends and didn’t have the required clothes with me.
This was no problem - I was dressed nice - nice button down, nice shoes, and jeans.
I have had no problem eating at the finest restaurants in NYC and London wearing this - and even less.
I would be shocked if abow tie didn’t count. I am sure there are some restaurants that strictly enforce this, but in places like NYC and London - with so many tourists - you’d probably have issues.
Sometimes I have been wearing a jacket - so I don’t know about those restaurants.
No one has ever treated me poorly at a restaurant based on my clothing in NYC/London (that I know of)
At one place where jackets were “encouraged,” and I didn’t have one, and everyone else seated in the room did, I insisted to the manager that he insist I wear one, just so I could try one of the jackets he had in a closet for this type of situation.
I found one that fit perfectly and looked quite good.
I alays think of a quick bit in Top Secret, where the hero is stopped by the maitre d’ because hes not dressed right, steps out to the side, and returns a few moments later with a stunning hand-tailored/fitted tuxedo.
1971; late 1960’s - early 1970’s. Them was the days. The kewl crowd dressed like this at fine restaurants. And you could always get anything you want at those places too!
