Haven't tried Chirchir but I have sure tried Choochoo🐔. Their fried chicken come in five flavours: Soy, garlic, sweet, spicy and original. After my Korea trip, I have since been quite skeptical about the KFC standards here in sg but I sure wasn't disappointed by choochoo. The double batter+sauce combi at choochoo made me gain some faith in the KFC here in sg and the food were decently priced too! Do try their lunch sets that come in the form of KFC+seaweed rice. I liked the yummy seaweed rice as well:)
