Me and my wife had lunch at Jardim dos Sentidos, meaning that we only experienced the buffet.
It was already a bit late (almost 15:00) when we arrived, so the food available on the buffet was not the freshest but it was quite acceptable.
I enjoyed the variety of somewhat more exotic food when compared to other similar buffets. There were plenty vegan options and of those, everything was quite tasty - especially the delicious papadums that we couldn't get enough.
I must say that I was pleasantly surprised by the warm and cozy atmosphere of the restaurant, with subdued lighting and some tables placed in nooks of the restaurant walls. There is an outside garden but it was too cold outside and besides it is allowed to smoke there, so we just stayed inside.
Like other reviewers said, I thought the food was pretty decent although not excellent. However, I must also say that I find it ever more difficult to be amazed by the food at any buffet unless I arrive very early to grab food coming right out of the kitchen.
Cons: Good food but not really excellent, Garden is a smoker's area
