So far I have only invested in Chopstix's delivery service. As a vegan, I am content with the variety of tofu dishes offered, as well as the choice to either order a large entree or to go with a combo meal. Sometimes the deliverer of my goods has called me to inform me that the car is outside my dorm--this is after me not able to hear anything on the other side of the line--and the car is not, in fact, waiting there.
I would personally advise against ordering the spicier dishes because my experience with those orders is over-filled with red pepper flakes instead of a variety of specs that add kick. Maybe I just don't order spicy Chinese food often enough to know better. Nevertheless, I have been very satisfied with my sesame tofu, regardless of the fact that it doesn't come with veggies in the combo platter, and I always have received more than one fortune cookie.
