SHOULD_I_BUILD HN?: Can't ever seem to figure out where to go for dinner?

SHOULD_I_BUILD is a new term I'm starting for micro-validation of ideas. Prelaunch, pre MVP, pre- leancanvas...pre anything! Is it worth pursuing, I ask?

My first one:

An app that I click a button, it tells me where to go get food. Remove the paradox of choice like you get with Yelp. It could pull data in from my credit card transactions to suggest "favorites", or "newbies", based on my purchase history.

Should I build?
