Actually there is. Most of the little restaurants (and they are really, really little) don`t have any kind of refrigeration so they use ice. Also, street vendors use ice to keep drinks cold. The ice vendors break these blocks into smaller pieces and sell them by the chunk. In the morning you can see pieces just sitting on the sidewalk by a door — delivered in the way milk used to be delivered in the U.S. fifty years ago.
