Could you give me some advice and opinions?

I'm going to show an American guy around Osaka and Kyoto next Saturday. He recently came to Tokyo for to study abroad and will come to Kyoto to hang out with me.
What I want to ask you is, where I should take him? Of course Osaka and Kyoto have a lot of popular must-see places, but I haven't heard an actual foreigner's opinions.
So if you've visited the two cities or are interested in them, could you tell me what(where) you'd had fun with, what made you feel impressed or what made you feel the differences fromyour country and what do you want to visit or do if you can?
Thanks.

I recommend Fushimi Inari Taisha because it's free! 留学生はお金が少ないと思う。（笑）Definitely visit Kyo Mizu Dera and Gion to get a feel of old Kyoto. Arashiyama is really beautiful too and the monkey park is so unique!

In Osaka of course you have to visit Dotombori and eat takoyaki. If your friend is an otaku, go to Den Den Town (Nipponbashi) because it's better than Akiba. Osakajokoen is really pretty too.

If you have time, I think visiting Nara is a good idea. The first time I visited Todaiji I was so moved that I almost cried. It's really a stunning place! And it's so easy to visit from Kyoto and Osaka.

And try to get your friend to try natto! 沢山外国人は納豆が嫌いですけど、おいしいよ！あたしは納豆が大好きです！（＾▽＾）
