Very tasty food indeed and quite authentic too (according to the four Chinese people in our group). We went in a reasonably big party and had booked a table. Unfortunately, it wasn't available on our arrival so we had to wait for 5 minutes or so and then were seated at a different, smaller table that had another one added on to it when the couple next to us left. However, this wasn't a particular problem.

We originally decided to go for the "Chef's Choice" option which would provide a two course banquet for all of us for £27.70 per head. After much deliberation with the serving staff (in Mandarin) it was concluded that it would be much cheaper if we just chose the dishes ourselves. The final price ended up as £17.50 per head including drinks and rice (for a 1 course meal).

After all this had been sorted out, we had a very pleasant evening. The staff were very attentive and friendly and the food was excellent. I'd highly recommend Zheng as a place to get authentic, tasty Chinese food at a reasonable price (if you order for yourself!).
