There are several mercados, street markets, in Xela, short nickname for Quetzaltenango. One of them is in La Democracia in zone 3. I like this one best. Because it is relatively cheaper than central market. There are more options. They are fresher. And apart from the vegetable market, there is also a bazaar where I can find other things, including clothing. It is one of my favorite places to visit when I have some extra time to kill or need to buy something. I like its liveliness.
