I will have to give that honor to Naan N' Curry. Why? After comparing it with other chicken tikka masalas from a variety of Indian Restaurants in San Francisco, Naan N' Curry's chicken tikka masala was more consistent than the others. Yes, you may have a good tikka masala at Tikka Masala, but the next time you come in, it tastes diluted. Therefore when I crave it, I go straight to Naan N' Curry, knowing it's going to be that delicious flavorful taste I specifically crave.
