Have you thought about either some guidance, or even a filter, for meal size?

It would be great to somehow either

- Get to the map from a city list

- refine the city to a neighborhood level

One of the reasons GasBuddy took off was that it wasn't just based on community reports; there was an incentive for gas stations themselves to accurately report their prices and keep them up to date.

It seems like you're trying to discourage businesses from participating (e.g. by not accepting sponsored placements), and that will have implications for your growth rate. I think you should look for ways to give businesses an active role, without eroding user trust in the recommendations, of course.

Think of the possibilities:

- Business can add coupons to its listing, making cheap food even cheaper

- Business can confirm a reported deal, adding to its credibility

- Business can provide full menu and a link to order takeout

I don't think any of those features would make users feel like the business is "buying" a listing it didn't earn.

They should add the cost of future open heart surgery to the cheap meal.
