We used to eat here quite often (2-3x per month), and have tried just about everything on the menu. Lately the dishes have just not been as tasty. Also, tonight when we went there, the portion sizes actually got smaller. When 2 people are eating for $18.xx, I expect to have enough food to fill me up.
We are both active people, so we eat a fair amount, but we usually have leftovers unless we share a dish. On this occasion, I left hungry after we shared 2 dishes. We asked the server about the portion size and he assured us "everything is weighed". The part omitted, presumably, was "now we measure out less". Another diner also complained about portion size while we were there. This place is emptier every time we visit. Doubt we'll go back again. Sorry Pei Wei, seems like you have run your course.
