Kaya toast is Singapore's national breakfast, and the people of Nanyang have added a Western dish of roasted toast to Kaya. Dried kaya sauce is made from eggs, milk, coconut milk and cane sugar, and most of the time colorful leaves are added, so the color is usually olive green, and the overall taste is burnt and crispy and sweet. Founded in 1944, Ya Kun is a small coffee stall that has become almost synonymous with kaya toast with its brown toast slices as thin as wafers and delicious kaya sauce.

Yakun is best known for its kaya butter toast, which is made with thin slices of toast, baked or charcoal-grilled until crispy like a biscuit, thickly coated with a layer of kaya paste, and sandwiched with a slice of cold butter, which must be freshly removed from the freezer and melted when heated. The cool and smooth butter of butter meets the warm toast, and the soft and sweet kaya sauce is clear but not greasy, with a slight coconut and colorful leaf aroma, which complements the first two pairings. Steamed bread is also available on kaya toast, which has the opposite of toast, the steamed bread is soft and steaming when served, and the butter and kaya sauce melt when heated, and the juice bursts when you bite into it. There is a toast set menu to choose from in the store, after ordering a single kaya toast, you can add 20 yuan to get two healthy eggs and a 240ml cup of coffee/milk tea. Healthy eggs are only three or four ripe soft-boiled eggs, which are beaten with a small spoon and stirred with dark soy sauce and white pepper, and can be eaten alone or dipped in toast, which is the most authentic Singaporean breakfast.

Ya Kun also serves some rice and noodle light meals, Hainan chicken rice is one of the signatures, the rice is slightly salty, with a hint of ginger paste; Each one is soaked in chicken fat, so the aroma is strong. However, the flavor of chilled chicken is still slightly inferior, the aroma of the chicken is light, and the meat is tender but slightly loose. Relatively speaking, fried rice full of wok flavor and distinct sauce flavor will be better than Hainanese chicken rice, but in terms of overall performance, simple meals are not as good as kaya toast.

Several of Yakun's branches in Sioux City are located in or near the mall, making them relatively convenient. There are not many people in the store, and the toast is freshly baked, so the food is served slowly, and the attitude of the staff is tepid. There is basically no waiting table for meals, but occasionally the smell of oil smoke wafts out, and the table is often dirty. If you're only ordering toast, it's recommended to take it away, but remember to eat it hot.
