Is flan sweet?

yes, it is custard with a caramel sauce.

In a basic flan that is made it contains per serving:

164 calories, 6 grams protein, 20 grams carbohydrates, 6 grams total fat, 214 milligrams cholesterol, 82 milligrams sodium.

There is 2/3 cups sugar in it.

Depending on the person who makes it, they could add more sugar if they like but then it would alter the flan altogether.

I wouldn't classify it as a spanish treat. it originated in Europe and is popular in Spain, but other places also.

But Yes flan is slightly sweet. not overbearingly sweet either which is nice :)

Flan is awesome, and sweet.... but you have to know how to make it, otherwise it will taste like nothing... i've had awesome flan, and then sh*tty flan, i mean it tasted like nothingness...

It is slightly sweet but not overly sweet. It has more of a milky taste than a sweet taste.
