I'm obsessed with this app Wine 'n Dine—it's like Instagram, but for food. You can post pictures of what you're eating and where you're at. Then whoever you follow, you can like it or press 'want to try,' and if you press that, it goes on a list on your profile, so if you don't know what to eat, you can just go to your photo gallery. Or let's say I wanted to try a sandwich my friend had in Italy: If I end up going to Italy and I'm close to the restaurant, it notifies me.
