my account was auto disabled after signup and email confirmation, and a phone number is required to request a review. Not everyone has a phone number you know ... The only reason I'd need a Facebook account is because the food menus are posted on a user account ( which isn't visible to those without a facebook account) instead of them being posted on a fb page like others do. So I guess that's one way for them to unawarely lose business. Also the app has change wifi&Bluetooth connectivity perms.
