Sergio's & Mariscos El Cata: The Seafood Table Locals Guard
Park Avenue · Family owned · Mexican classics and Sinaloa-style seafood
Dani · 6 min read
A family-run room on Park Avenue where a Sinaloa seafood program quietly outgrew the building. Order one plate of mariscos, one classic, and understand the town better.
Why you should go
Sergio's is the answer for the guest who wants the meal locals actually drive to, not the one printed in the resort brochure. Sergio and Alondra Hinojosa took ownership in 2023, and in 2025 they brought in Mariscos El Cata, the Sinaloa-style seafood house founded by Catarino Buena Castro, as a partner inside their own dining room. The result is one kitchen with two identities and an ambition well beyond what the casual Park Avenue address suggests.
Start with the Botana del Cata, a cold seafood spread of shrimp, aguachile, octopus, scallop, and tuna under the house black sauce, and the table understands immediately that this is not a standard Mexican menu. From there the classics hold their own: a 25-ingredient Mole Michoacano, handmade tortillas, carnitas, and a whole fried fish worth passing around.
It is also the rare Park City restaurant with a weekend breakfast worth planning around, which makes it useful for a Saturday morning before the mountain or a slow Sunday after it. Come for the seafood, stay for the fact that someone here knows your name by the second visit.

When to go
- Best first visit: Tuesday through Thursday around 5:30 to 6:30 PM, before the dinner rush settles in.
- Best for seafood: dinner, when the Mariscos El Cata side of the menu works as a shared table.
- Best weekend move: Saturday breakfast or an early lunch, when the room is at its most local.
- Best for: adventurous eaters, families, groups, seafood lovers, and guests who want somewhere less tourist facing.
- If the table is split between classic Mexican and seafood, this is the easiest recommendation in the category. Both sides order well.

Local intel
- The seafood partnership is the reason to revisit if your memory of Sergio's is several years old.
- The menu is unusually broad. Order one seafood plate and one classic Mexican dish so first-timers meet both identities.
- Do not judge the meal by how casual the room feels. The culinary ambition runs well ahead of the building.
- Sergio and Alondra are the story here, which is why this recommendation carries a person and a history rather than only a menu.
- Weekend breakfast is a second reason to come and the detail most Park City Mexican guides miss entirely.
