El Pueblito Reviews
An authentic Mexican grocery store. Their chorizo is delicious, flavourful yet not greasy. They also have good flank steak that has been tenderized which we used for carne asada. Their store has fresh vegetables like peppers, cilantro and avocado in a refrigerated section at the front. The woman behind the store counter is very helpful and friendly but her English is a limited, so bring your phone to help translate. She does not mind.
They had every spice and seasoning I was looking for. The fresh vegetables looked amazing and I found a couple of snacks I have been missing for years. If you need any Mexican spices or chiles, they have them reasonably priced.
