Ordered the all toppings mazesoba (bottom, $15.80) and char siew mazesoba (top, $13.80). I personally like the noodles (thick, chewy, QQ) and sauce, and there is also a free upsize option to 1.5x noodles. Quaint Japanese eatery right outside Bugis MRT- it wasn’t crowded at all on a Saturday afternoon.

Total for 2 pax: $18.60 using BB 1 for 1.
Do note that you can only order 1 all toppings mazesoba if you are using BB.
