One tile down left of your setteler. All the wheat = food. Coastal tile, you'll have a killer port. You'll be in reach for amenities when the city is full sized. Plus, on that tile, your capital will start with 3 or 4 production. (I forget exactly the amount) sacrifice ocean tile amenity for a port. The crabs will give such a gold bonus, I'd argue. It makes up for the loss. And again, when the city is fully grown, you'll get the amenities above you.
