How does the 5to7 mango soufflé taste and feel?

What I ordered on this revisit was the mango soufflé at 5to7 Seongsu Main Branch. It was so fluffy and thick that it wobbled just from resting a fork on it, and it melted in my mouth exactly like the first time.

That melt-in-your-mouth texture was exactly the same. Soft, moist and gently sweet, it all came together into a really satisfying bite. I could see why this place is famous as a soufflé spot in Seongsu.

Are the mango and cream toppings too sweet?

The mango and cream served with the 5to7 mango soufflé weren't overly sweet, so I never got tired of it until the last bite. The freshness of the mango went well with the sweetness of the soufflé.

It wasn't only the soufflé that was good. The mango and cream toppings were satisfying too. The cream wasn't too sweet either, so it was easy to enjoy. Personally, I sometimes get sick of desserts quickly because they're too sweet, but here I could enjoy it to the end. Maybe that's why it's not a one-and-done place but one you think about again. In fact, I came back because I remembered the taste.
