Meidi-Ya Japanese Supermarket at Great World City is praised for its extensive selection of authentic Japanese products, fresh sushi, sashimi, and high-quality groceries, providing a supermarket experience reminiscent of Japan. However, reviews highlight that recent changes have led to a smaller store with limited space and fewer varieties compared to previous locations, accompanied by higher prices and occasional service issues. The store remains a favored destination for Japanese food enthusiasts seeking premium ingredients and unique items, despite some concerns over pricing and store size.
