Have been there 4 times over the past 5 visits to Mazatlan.
This restaurant has been in business since 1960 and is probably the oldest continuous operation in town.
Set in an open courtyard; very romantic very charming.
Owner is gracious, food is exquisite.
Zarandeado fish is super, but the Zarandeado shrimp (giant prawns split open) can't be believed!
Generous pour for house wine and house daiquiri is powerful.
No English spoken, but none really necessary.
Have not seen any tourists there, but is frequented by local families and business people who seem to know where to eat.
Definitely will return.
