My daughter had an idea that could make Open Menu Search much more useful. She asked me who around here delivers, besides the obvious Chinese & pizza. She wished there was a restaurant search engine that could answer that. When I checked the advanced search on Open Menu, I noticed there was no options for it.
In advanced search, you should include check boxes for delivery and take-out, so if someone only wants to see all the places in their neighborhood that will deliver, they can easily do that.
