We have loved eating at Panda Inn over the years when we're in southern California, and we've have had the Sunday Brunch at the Panda Inn in Pasadena several times , so we decided to try the one here when visiting San Diego. There were several different types of dishes, which were well prepared, and very good. They even had an abalone and bok choy dish, which was not something we'd seen before. It's very difficult to make dishes on a buffet be as good as when they're ordered off of the menu, but Panda Inn does about a good a job of it as we've seen.
Even so, there were a couple of things that weren't what we would have hoped for: the Orange Chicken, which is one of Panda's signature dishes, was a lot of fried batter in relation to the amount of chicken in each piece, which is not what we'd expect from a restaurant of Panda Inn's usual quality. Another thing that was a little disappointing was that there were three salads, a smoked duck and papaya, a Thai beef, and a third one (which I don't remember). The meats and the sauces were all different, and all very good, but they all seemed to be served with the same assortment of mixed greens; some variety there would have been nice to make the three dishes more distinctive.
Also, they seemed to be slow to respond to the rush of people when they first opened, and so for a while, almost all of the warming trays were empty, which created some frustrated customers. Now, to their credit, I think they cook even their buffet dishes in relatively small batches, which is one of the things that keeps the quality so high. Eventually, they caught up, but Panda Inn has been doing this long enough that I would have expected them to be able to do a better job of staying ahead of things.
In summary, we definitely plan on going again when we're in the area, and we wouldn't hesitate to recommend it to others, but there were a few things that were "opportunities for improvement."
