There are not many Asian places that will deliver to the Polish Hill area, so I occasionally order from Wai Wai. The food is OK and it's cheap with nice sized portions, where you'll most likely have some leftovers. The meals I've had are typically what I would expect of fast-food American Chinese food. I've had the General Tso's, Chicken & Broccoli and Shrimp Lo Mein and a few others and they were all good. My favorite part of the meal was the Crab Rangoons. You can't go wrong with fried dough and cream cheese, but I've been very disappointed at other places where they are dry and practically empty on the inside. Their rangoons actually have a good amount of filling.
Good for a quick, cheap meal.
