If you take the literal meaning, then this here, is not a xiaobao. It's a dabao 大包 or big bun! (Actually the siopao around the Philippines are actually dabao 大包, only a few have the small buns.) And what's inside makes it, in my opinion, a hen dabao 很大包 (very big bun). But enough about the Mandarin lessons.
Why did I say it's a big bun? Because it is about 10 cm in diameter (well, wiki says a dabao 大包 measures 10 cm in diameter). And why "very big bun"? Because this siopao—Taitong's Special Siopao (Php62)—has not one or two but five fillings: asado, bola–bola, Chinese sausage, plain siomai, and salted egg. Boring it certainly isn't. Taitong's Special Siopao is a fiesta in a white bun. Hen hao chi 很好吃—very delicious!
Taitong offers not only siopao—the "Foods" in Taitong Steamers Foods clearly says so. Taitong also has a bunch of dishes up the chef's sleeve. Check out the menu below.
