Pizza or Italian in Delhi?
Flavors- Moolchand flyover market - Highly recommended; a long standing establishment; As close to 'real' Italian as you can get there
The Big Chill - Kailash colony one (not Khan Market). Thin crusts, some novel creations and I have never had a problem with the quality.
Pizza Square - Chittranjan Park - USP is a square shaped pizza, but the taste is not too bad, though the crust does get a bit too thick for me
