Easy to use
I've only used Hungryhouse a few times and so far no problems. Even found a great new place nearby that I didn't know existed before using HH. Website is easy to navigate and I like that you can save and easily re-order entire orders as I tend to order the same things from the same places and only vary when I'm trying a new place. Now they just need to give us a Blackberry 10 version of their mobile app and I'd be a happy customer!
