Diggin, Imperfecto, Sky High, Kylie Experience, Thai High, Olive, Dramz, Woodbox Cafe and Turquoise Cottage are some good options
I prefer Sandoz & Diggin for dining in South Delhi
Budget info would help.. Pa Pa Ya is a good option. Looking for something more pocket friendly, go for Diggin. Something very unique and meaty, go for H Man.
My forever fav place is Leo's in Vasant Vihar. They do the BEST pizzas in Delhi!!!
Just go to hauz khas village and I'm sure you ll be amazed.
