According to karabau, this place has closed down. Sad siya. (updated 12/30/07)
Riding around Makati late one night, I came across Good Origin Bento along Pasay Road. It looked new and cheap - how could I resist. I ordered the niku curry soba udon, which wasn't too yummy. But then it cost only P75 so I shouldn't be complaining. Also on the menu are your usual rice toppings, gyoza, and some salads.
Good Origin Bento supposedly closes at 5am. Seems like a decent place to fill your stomach after a long night of partying, when hot and cheap *almost* make up for taste.
Along Pasay Road, between the corners of Amorsolo and Paseo de Roxas. You can't miss the huge neon sign.
