Don Don Donki aka Don Quijote is a popular budget store in Japan that sells watches,clocks, clothings, toys etc etc to food items like cup and instant noodles, coffee powder, freshly baked sweet potatoes, kimchi and many others at huge discounts.
We bought a few items like kimchi (S$2), cream puffs (90cents each), grated cheese, instant coffee powder etc. They are all cheaper than those sold at other supermart.
Don Don Donki has opened a store in Orchard Central, Singapore last year. It is very popular with Singaporeans and tourists.
