I know there are a number of ways to order food from restaurants online: Foodler, GrubHub, Seamless, as well as LivingSocial. Perhaps there are others of which I'm not aware?
Anyway, I'm curious your experience with these different companies. What are their relative merits (or demerits)? How did you choose which one to use? Do you use more than one on a frequent basis? Any other information that might be helpful for a user to know?
I'm in Watertown (if location is relevant), but I imagine this information might be helpful to anyone ordering food in and around Boston.
