I believe the first KFC was situated near the waterfront (Saigon River) at the Central Commercial District. The second is behind the New World Hotel near Pham Ngu Lao St. Hanoi just opened its first in 2008.
It is my practice to sample KFC and McDonald while overseas whenever possible. Though not enough to generalize due obviously to lack of sampling and also lapse of time in between samplings.
But this KFC (behind New World Hotel) has very good stuff. Chicken pieces were not oily, tender, warm and tasty. The salad was good. Greens were fresh.
The interior is clean and well designed and finished with high quality tiles. Staff was well trained. The other good thing is it's well maintained as this one is at least 3-4 years old.
It's the Christmas Season
