This is the best place to buy fresh fish. It has a vast selection and it is easy to purchase. It is not for the squeamish.
You must use the plastic "mitten" to pick up your fish and put them in a plastic bag. Then, you take the fish up to the counter and it is weighed. If you want the fish cleaned and cut they will do that there.
It is primarily a Phillipino market. If you need Phillipino specific sauces, spices, etc. this is the place.
Another bonus, if you play Pokemon Go, this is the place to catch rare water Pokemon. The store and parking lot are full of them!
