To avoid this conversation... generally if someone asks me what I want I will give a couple of options like Mexican or Italian... or American or Japanese. And then follow it up with, "you pick the place though."
That way there is some direction and the other person gets a say too. It seems to work well. Plus, if he's one of those men who insist on paying and not splitting the check (I don't date a lot... but when I do this happens to me a lot) then at least he's in control of how much he spends based on the place.
But really, I kind of like everything, so most times I am flexible
