Regency Chinese Supermarket

The store despite its small side is quite compact with all kinds of Chinese, Japanese and east Asian products. He even has a downstairs if you want to look for noodles and treats.

It even has some fresh produce and some vegetables. So if you're looking for some ingredients and want to make a nice Chinese meal. Pretty good choice selection.
And it stays open later than Red Chilli so that's a star.

However in terms of price seen I think regency is more expensive than red chilli depending on some products. Their only MSG which is £3.99 if I recall is either £1.99/£2.99.
So it's best if you go to Both stores and compare prices.

Very diverse products from Asia. You can find everything you are looking for.
