1. I have a reservation for two at five o'clock today.But I think I should be alone.Are you okay? 2.Do I have to wear a jacket? I'm here on a trip, but I only have padding.ㅜㅜ

Yes I'm great. Please confirm your reservation and how many guests. Suit or Sports Jacket is appropriate.

It doesn't matter if you're alone Dinner may be a bit of a problem, but it doesn't matter if the outside coat room is padded and the clothes inside are neat. You can go there alone. That's not a problem at all. It can be a problem at dinnertime but you can put your padding coat at the coat room. Enjoy!
