We subscribed to Plated for about 3 months, and loved the food. However, of the 12 deliveries, only 2 came during the 8 am-8 pm window. We had deliveries that didn't come at all, some that came in the middle of the night, and some that came a day late. Most came around 10 pm, way too late to use for dinner that day. And none of the delays were due to storms or issues outside of Plated's control. We live in the Boston metro area, so it's not as if we're far from a transportation hub, either.
They gave us a few credits in response to complaints, but were never able to sort out the delivery, so we ended up cancelling.
So, zero stars for delivery and the convenience the promise. You can get good food elsewhere without the hassle.
