This is a HUGE Asian Market filled with all kinds of unique goodies at a great price. You can find rare fruits here such as durian, jackfruit and lychees, a huge selection of assorted teas, strange sea creatures and so much more! I love getting freshly-squeezed sugarcane juice when the little shop inside is open. If you go on Sunday they have vendors that are not usually there making delicious food!
If you are interested in actually buying and growing your own exotic fruit, I recommend checking out Exotica Rare Fruit Nursery in Vista!
