Order-out casual lunch in Huntingdon Valley, PA
I haven't been there in about a year but Taste of China is in a shopping center at the corner of Philmont and Byberry. They make good chinese food.
For platters and italian food (they also have pizza but its not as good as the place I mention below) Original Village is technically in Philadelphia but not by much. Its on Sandmeyer Lane off Red Lion Road. They have very good italian platters like manicotti, raviolli, lasagna etc.
For pizza, Iliano's on the other side of that shopping is very good. There is also an Iliano's in the Justa Farm shopping center on County Line Road.
I have not been to Riccardo's but I know a lot of people who like it.
