Mia Cole: Before you eat with the locals, have your first meal at Jack's Cafe. It's a nice slow digestive introduction to eating out in Cusco. Plus, it's great if your first meal is breakfast.
Green Toad Bus: You can see the guiness sign from the Plaza de Armas. Irish Pub, good music, Happy hour daily, a very busy place, good cheap food, a good place to meet up before hitting the night life.
