About a dozen restaurants in Barrio China back up onto a walkway closed to all but foot traffic. It's a great place to eat outside. The food is passable and cheap. The girls walk up and down this half-block long walkway, flirting with foreign diners. Take a table, order a drink and/or food and they will find you. There are also several chuchos (men who procure women) who work the strip. I once put an order in for a girl with one, describing exactly what I wanted. He went away and returned a half hour later with my take out order. She was not a street girl.
