The restaurant need's some improves. The food was good, but with poor presentation. The staff was excellent, namely the waiter.
The guy behind the counter, which as I understand is the son of the owner of the restaurant, has a horrible look. It seems even a beggar. Has even improve the look. It is essential for proper functioning.

Cultura dos sabores is a good vegetarian restaurant where you can serve yourself and eat as much as you want. I like the fact they have swings inside!! Recommend it!

We were excited after reading good reviews but the food was very bad. All warm dishes were cold, had no seasoning or flavour whatsoever. The rice was undercooked. Cold buffet wasnt horrible, but also no taste... Very dissapointing even for 10€. Never coming back and would not recommend. First time in my life that ive been out to dinner and didnt enjoy it, first time ever writing a bad review anywhere. ( we told them it was bad, and they laughed at us and said it is great food and it was because we are not from portugal)

Was blocked by the restaurant facebook page for no reason at all.
Only shared in local portuguese vegetarian and vegan groups their facebook post where they publicited non-vegetarian option.

Was supposed to give a second chance since our first time there was not really that pleasant and average food for an expensive price (cheaper buffet at other places like daterra and pé de arroz).
But won't go there again.

Shame on that attitude
I do not recommend this place to anyone.

Once entitled as vegetarian/vegan restaurant, started serving meat meals to christmas group meals. Local Oporto vegan and vegetarian comunity complained, to what the restaurant facebook page responded that did not identify with "radical ideologies" and removed user comments on it.
