Restaurant in Buenos Aires Province, Buenos Aires, Buenos Aires
Chichilo Mariscos
A legendary Mar del Plata seafood restaurant with decades of history, Chichilo is the place to eat the city's finest fresh fish and shellfish. The cazuela de mariscos (seafood stew) and langostinos al ajillo are unmissable.
Chichilo Mariscos is a legendary Mar del Plata institution that has anchored the city's seafood dining scene for decades, serving the finest catch from the South Atlantic at its address on Avenida Constitución in Buenos Aires Province. Mar del Plata is Argentina's most important fishing port, and Chichilo built its reputation by sourcing directly from boats working the cold, nutrient-rich waters off the Patagonian shelf, ensuring a freshness that few inland restaurants can replicate. The cazuela de mariscos — a slow-simmered seafood stew combining prawns, mussels, squid, and white fish in a saffron-and-paprika broth — is the dish that visitors mention most often and that regulars consider essential on every visit. The lenguado al vapor (steamed sole) demonstrates the kitchen's confidence with delicate technique, allowing the quality of the fish to speak without heavy saucing. Other signature preparations include langostinos al ajillo (king prawns in garlic-infused olive oil) and grilled octopus benefiting from a long tenderising brine before meeting the plancha. The dining room has the feeling of a comfortable maritime parlour: low lighting, wooden panelling, framed photographs of Mar del Plata's fishing fleet, and a gentle noise level that permits conversation without effort. Tables are generously spaced and well suited to leisurely lunches. The wine list prioritises crisp Argentine whites, particularly Torrontés from Salta and Chardonnay from Patagonia's Río Negro Valley, both of which complement the seafood menu well. Service is attentive and the wait staff can advise on the day's freshest arrivals. Chichilo operates a traditional split schedule, with lunch from noon to 3:30 PM and dinner from 7:30 PM to 11:30 PM. Reservations are strongly recommended for weekend evenings and throughout the summer high season from December to February. Walk-ins are often possible at lunch on weekdays, when the dining room is quieter and the set lunch menu offers good value for two courses with a glass of wine.

- The cazuela de mariscos serves well as a main for one but is excellent split as a starter between two people

FAQ
Does Chichilo Mariscos serve meat dishes as well as seafood?
The kitchen focuses overwhelmingly on seafood, which is the restaurant's identity and strength. A small number of grilled meat options may be available, but guests seeking an Argentine parrilla experience will find the restaurant's meat offer limited.
Is the restaurant safe for guests with shellfish allergies?
Shellfish is central to most dishes and the kitchen handles large quantities of prawns, mussels, and crabs daily. Cross-contamination is a real risk. Guests with shellfish allergies should communicate clearly with staff before ordering and consider whether a seafood-specialist restaurant is appropriate.
Is Chichilo suitable for children?
The restaurant is family-friendly, with a relaxed atmosphere during lunch service. The menu includes simply prepared fish dishes that suit younger diners. High chairs are available on request.
How far in advance should a reservation be made?
Weekday lunches can often be accommodated with same-day or one-day notice. Weekend evenings and any visit between December and February require a reservation of at least three to five days in advance.
Accessibility
The entrance on Avenida Constitución has a low step at the threshold. The main dining room is flat and accessible with sufficient aisle space for wheelchairs. Guests with mobility requirements are encouraged to contact the restaurant when booking to secure a table near the entrance.
