I am coming to SF from NYC for a conference this week. I called to book Jai Yun for dinner Thursday evening. When I said I'd be only one for dinner, they said they are closed on Thursdays, can I come on Wednesday or Friday? They finally asked that I leave my phone number and they'll call me back if there is availability. While I have never been to the restaurant, I am certainly aware of their menu policy. Has anyone ever heard of this? Am i being refused service because I am a solo diner? If so, I find this infuriating.
