There are many more varieties, as you said. I am literally about 100 meters from maybe 5-6 varieties of bananas and 10-12 varieties of mangoes. There are 4 varieties of dragon fruit here too, all excellent.

The cheaper varieties of mangoes are similar to what Americans are familiar with, but much more consistent. Mangoes grow so readily here that in season I can get a kilo for $0.25 and they're always perfectly ripe. There is a more expensive variety that is purely sweet and has a more gelatinous texture, and it feels "decadent" in the same way that a rich chocolate cake does.

The bananas are way better, especially some of the smaller varieties that have a thicker consistency. There are cart vendors everywhere here that grill those small bananas and sell them on sticks.

And then there are many others in the markets, a lot of which don't have common names in English but all of them are great really. It's so cheap that in my diet I eat fruit instead of rice or bread as a carbohydrate source. Even most imported fruits are pretty reasonably priced, so you can still easily find things like apples, champagne grapes, cherries, etc.
