When we started going to Pei Weis restaurants years ago, we really liked them as a faster, cheaper alternative to PF Changs even though the menu is more limited. But in recent months I have been disappointed by the food quality and portions of the some of the dishes. But of course the prices have steadily increased.
On our last outing, we ordered the asian chopped chicken salad and asked for extra chicken. We did takeout and when we got home saw they there was barely any chicken on the salad much less the extra portion that they charged us for. I called them back up spoke with the manager who apologized and prepared another portion of chicken for me to pick up- it's hassle to return to a store to get what you were supposed to get the first time.
Otherwise, I have noticed that their Pad Thai and Rice Bowls have gotten skimpy on the meat as well and the egg rolls are smaller. Overall, I am not sure what you get is worth the price. You are probably better off at a local Chinese restaurant.
