I often find myself getting in to a city fairly late in the evening for a conference/work meeting. Given I'm often staying in "conventionland," it's usually not an option to get a decent, local restaurant meal. I am almost always disappointed by a hotel restaurant.
I'm in San Antonio, and stumbled on this great business- https://www.thebikewaiter.com/ Their website included a large lists of restaurants available, many that seemed to have legitimately good reviews (this is the first time I've been to this city, so just inferring). The delivery guy was really friendly, and the food came more quickly than promised.
I wish every city I have to travel to for work had a business like this.
