Finally got the chance to try the burger from @hambaobao! Went there on a weekday afternoon, just before they open and managed to avoid the snaking queue which followed after.

Generous chunks of crispy Siow Bak with english mustard, hoisin sauce (reminds me of Peking duck!!) and cucumber sandwiched between two soft, buttery buns. Also added the Hand-Cut Fries for just $2.50. The kinda burger we never knew we needed. Love it!
