Just from the first page I found this one, "A restaurant that does food for when you feel too sick to eat real food" which is interesting because normally restaurants are not eager to cater to sick people, but if you combine it with home delivery there might actually be a market.
Once I was out to dinner with my boss and his wife was sick at home. He asked the waiter for a to-go order of “something very mild and bland”—I think the result was steamed vegetables and rice.
I found this really interesting at the time because most restaurants wouldn’t like to describe any of their food as “bland”! But sometimes that’s exactly what you want—if you’re sick, hung over, a picky eater, or very sensitive to textures/flavours (e.g. with ASD)—and you may not have the energy or time to prepare something for yourself.
