Dinevore Beta recently launched, giving users a new utility for choosing where to eat. Based on friend recommendations as opposed to crowd-sourced restaurant reviews, the site allows you to follow friends’ (or critic’s) feeds and see the food they are enjoying or interested in. You can also share you own food likes and desires, letting friends give their input on your choices.
