We had a takeaway from China One during a recent stay in Davenport. The food was made quickly whilst we waited and the service was great. Everyone was very friendly indeed. There was a family having dinner in the restaurant whilst we waited and we did feel a little awkward as we felt like we were encroaching on their meal but they didn't seem to mind too much. We were gone as soon as the food came out anyway.
The food from China One is amazing - really tasty and they have a great range of food on the menu. The rice is cooked perfectly and the prawn crackers are some of the best I have ever had. The portion sizes are absolutely huge so you can definitely share them between a couple (or more) people. We made the mistake of ordering one meal per person plus one portion of rice per person too - this made it very expensive but we realised when we were back at the house that it was because we bought far too much. I think it's still a LITTLE bit on the expensive side, compared to UK prices, though.
All in all, we would definitely eat there again (as takeout) as the service is great and the food itself it fantastic which is the most important thing. Well done China One.
