None. Use the restaurant's own ordering system whenever possible. But I understand that often these systems tend to be not as good. My family recently started a small takeaway and currently we rely entirely on JustEat/Deliveroo for orders. They take a killer commission per order and you always have to have an offer running on top to compete with incumbents who are favoured in terms of listing order. In the end you end up getting barely 50% of your list price. They can barely make ends meet. Luckily they have me (software developer) as someone who can create an online experience that rivals these big companies but competing with billion dollar companies on marketing is always gonna be a losing battle.
