Summary: don't expect that you can change any order even with offering to pay & even if it already an option and then paying for it : such as adding more vegetables. If they say they will do it for a fee , don't expect that they actually will.
Quality of food is ok - not great, but by no means terrible. At least they offer delivery for small fee. Delivery time is normal -45 minutes.
Ive ordered 2x and same problem both times, 2nd time i was assured on phone that the order would be correct, but it wasn't.
