MOS Café (The FOREST branch) is a Japanese-style fast-food café selling hamburgers and rice burgers inside a shopping mall in the Mong Kok district of Hong Kong. Its limited-time eel rice burger uses a large eel coated in a thick sauce, with the rice bun grilled until golden. Every item is made after the order is placed, so the fries and burgers arrive hot. The menu is picked up at the counter and can be taken to the table.
