We stayed in Hisaronu 5 times, we liked it very much but thought it was noisy at night in places. Each to their own. I am sure you will like it and you can get to Olu Deniz, and Fethiye easily from there. Also try going to Kaya. We walked there a couple of times. Its a fairly long way on a hot day but I enjoyed it.
Try Shine Indian and Dragonaro Chinese. or Robin hood, White Man, Olive tree. Do a search for other places in Hisaronu. There are plenty of eateries depending on taste and budget.
Enjoy and report back

BTW you can catch a dolmus to Kaya. They are once an hour till the season gets busy and then every half an hour and you can flag them down en route.
