Working well for me so far
I have only recently started using Hungry House and so far so good. Unlike some other services the same, HH don't charge you more than the regular prices for each item.
I like that you get an email when the order is accepted at the restaurant so you know order has arrived and been seen at your restaurant.
One downside, where I live it only shows one place to order from, unlike another well known provider. Luckily where I wish to buy from is the one showing. Maybe more recruiting is required.
