In short, Forkable is "Pandora for Lunch". AngelList profile: https://angel.co/forkable
My email can be guessed from my first name, "Joe"
As for the "X for Y" meme, I agree they tend to oversimplify. Nivi of AngelList provides compelling arguments why they are worthwhile anyway: http://venturehacks.com/articles/high-concept-pitch
As to your startup - Pandora is a streaming radio service which actually, you know, streams radio, as a service. Emailing lunch menus (or calendars, or whatever) is not as to lunch as streaming radio is to traditional radio, so your "X for Y" makes very little sense!
Anyway, I'm surprised you don't see how this particular comparison holds. Pandora auto-suggests and delivers musical content over the course of a few hours or so. Forkable auto-suggests and delivers "nutritional content" over the course of a week or so. Does that make sense to you?
But hey, perhaps I'm too stupid for your startup (usually I just make a sandwich for lunch, so I'll probably cope either way!).
The image of people printing out emails and eating them is pretty amusing, though. :)
OK, great, you deliver food. If your AngelList profile is your main publicly visible page at this point, you should - in my humble opinion - make it really clear what it is your service actually does: however slowly I read "we send you a calendar of lunches from awesome local restaurants", it doesn't suggest to me that you actually deliver food. The second paragraph does mention delivery. Make your copy accessible even to people who read quickly and don't care very much and you won't go far wrong (with your copy, anyway!).
