looking for good sichuan in north orange county
No good Sichuan in North OC. Go to Chongking, in the 99 Ranch plaza at Walnut and Jeffrey in Irvine. Even in rush hour it is only 20 minutes' drive from, say, the 57 and Ball Road.
They have a very good cold appetiser table. I did not enjoy the mapo tofu, but the other hot dishes I have had have been excellent.
