We arrived at an empty restaurant, a man came out, looked at my husband and me and asked us to leave without explaining anything.
It's kind of strange in Armenia, where we live all the time.
Then I called the receptionist and she politely said that there were places and there was no need to book, we could come.
In general, there may not be a place in an empty restaurant, you can be kicked out at any time
So, I don't know about how delicious the fish is here or something else
