One service that I love and used many times is GrubHub.com to find restaurants delivering late at night to order. Another competitor that I've seen ads for but have not tried is seamless.com

I just (3 days ago) moved into a new city (Brighton, England) and this exists here[1]. It's amazing, seriously. I assume there's all manner of licensing crap associated with doing it as a big company (which is why the people that do it here are very low-key and haven't expanded beyond this city) but something like this globally would be so great, although there's little room for making money unless you do the aforementioned licensing.

I've used them twice so far, there's an extra time associated with delivery because they first have to go to the restaurant and order, then wait and deliver to you, but it's worth it, although I've only used them for McDonalds and Burgerking so far, both were delivered in ~90 minutes. They support about 100 different places, fast food and real restaurant.

http://www.doorstepdelivery.com/ does it here in Florida, use them quite regularly.

That this seems to exist in a number of areas suggests that it's hard to scale outside of a certain geographic area.

These guys are working on this exact idea. But the options seem limited.

foodler.com and mixmenu.com offer this service in my area for (often) a small delivery fee. but then they have deals, so you often end up saving money. I think that the delivery fee model beats the fixed subscription model in this case.

wow, for crowded city like New York City, where there is thousands of amazing restaurants where they _dont_ deliver, this is a huge market and amazing idea coming together!

GrubHub.com my friend

eat24hours.com does this well in some places.
