I posted this a while back, but didn't get any feedback. So read the quote, and pretend that it's a new question.
Sorry!

Here I was waiting for you and you seem to have been waiting yourself.
Well, as you can see, you are on a wheat. All bonus food goes away if you settle on it. I guess it's bad for growing plants if they have a city unloaded from a backpack on top of them. Shield bonii also disappear, but can come back after you have a city, or something, not sure about that one. I am sure they go away at least in the begining, but we aren't talking about shields right now.
Well, then short answer is off the wheat.
Long answer, there are 8 choices, 3 are off the river, which usually is a bad idea. Of the 5 on the river, there's a wheat, a forest, 2 Bgrass and a grass. Of these the best to settle on would be the grassland. So, move straight south.
If you're wondering about the wheat straight north, yes it wont be in the capital radius, but that doesn't mean the second city can use it! You don't need 3 wheat in the capital. I'd say just NW of the forest that's NW of the settler might be a good spot for the second town already, of course there might be horses nearby. That's very important. Japan is the
only civ that can see a strategic resource from the begining.
Also, moving south puts us on the south side of the river (Duh!), which according to the minimap is the way our troops are likely to be marching. Until Engineering, when bridges magically appear everywhere even places you don't own, it costs a whole point to cross the river and that slows things down. But that's minor compared to the other stuff.
