I love the idea, but a quick glance (randomly at SF) reveals entries that aren't "meals" (IMO, anyway) but rather snacks - like two spring rolls for $8, or a slice of pizza for $5.53. Also, the days of a $1 slice may have (long) gone, but $5.33 for a slice seems median at best, not "cheap".
Have you thought about either some guidance, or even a filter, for meal size?
