If you wish to have an Indian lunch as far as the peppercorn grows, then I would recommend Sahakari Spicefarm in Goa, India.
Sahakari Spicefarm is located in Ponda in South-Goa and it is very suitable a sight for a traveller, who wants to get to know Indian nature and Indian plants and spices. Though it is a little bit difficult to reach, and easiest by a taxi. –
The Sahakari Spicefarm restaurant was located in the middle of the forest, nearby the entrance of the Spicefarm.
Back in 2014 the lunch in Sahakari Spicefarm restaurant consisted of rice, lentil sauce and chickpea dal, and the roti was replaced by the traditional Goan pao-bread, baked with wheat and yeast. After the lunch there was also this red ayurvedic types of drink, usually served with Indian thali, and consumed after eating. It is supposed to ease the digestion.
Food in the Sahakari Spicefarm restaurant was tasting fine. There were a few fans in the restaurant cooling the customers during the hot tropical days of February. Overall I would give four stars out of five for this restaurant, since the surroundings were so tropically charming.
