A seafood and sushi restaurant in Cancún

August 13, 2026 · The Menu · MERO 18

Every group has this argument. One person has been dreaming about oysters and something cold and citrusy all week; another wants sushi and nothing else. The easy fix is for someone to give in. The better fix is a seafood and sushi restaurant in Cancún where nobody has to. That's the idea behind MERO 18: a cold bar built on the day's catch and a sushi bar working out of the same kitchen, on Avenida Carlos Nader in downtown Cancún. Below is the honest tour — not every line of the menu, just enough to walk in knowing what you want.

Raw seafood and sushi are the same argument

They look like two different cuisines. They rest on the same foundation: fish with nowhere to hide. A ceviche and a piece of nigiri fail for identical reasons — product that arrived late, was held warm, or was cut carelessly — and they succeed for identical ones: careful receiving, a sharp knife, and very little time between the cutting board and your table. A kitchen that has solved that for the cold bar has already solved the hard part of sushi.

That's why "a seafood place that also does sushi" undersells it, and why we prefer the term sea bar. The catch comes through one door and leaves in two directions: the same Caribbean white fish can end up sliced thin in a tiradito or draped over a roll. That Caribbean–Japanese turn isn't a marketing idea bolted onto a menu; it's the logical consequence of buying well.

A tour of the menu, section by section

We won't reprint the full menu here, but you should see how wide it goes and where each craving lives. Prices in Mexican pesos.

To start: appetizers and tostadas

The most us way to begin is the Shot Shot Shot ($170) — a fresh oyster shot, citrus and heat, served in a glass skull. The most diplomatic is guacamole in a molcajete ($150), which gives the raw-fish sceptic something to do. The tuna tartare ($180) bridges the two camps. Then the tostadas: tuna and salmon at $190, conch at $200, shrimp at $170 — a bite and a half each, the cheapest way for four people to taste everything.

The cold bar: ceviches, aguachiles, tiraditos

The heart of the house. Ceviches come three ways — chile ash, traditional, or mango curry — with catch of the day ($180), shrimp ($200) or conch ($220). Aguachiles come spicy green, Sinaloa-style, or black, with shrimp ($200) or conch ($220); the black one is what guests keep writing about. "The black aguachile is a delicacy," Luis T. put it on TripAdvisor, and we've never found a better summary. Tiraditos close the section with Peruvian-Japanese technique: tuna ($235) or salmon ($290), dressed in leche de tigre or ponzu — your call.

Oysters, by the piece, shucked to order

Cold oysters are sold by the piece ($50), so you can build a tasting flight without committing to a dozen of anything: natural, ponzu, shaved, green aguachile, salsa diabla, cocktail-style or black. They're opened in front of you, not before you arrive. Prefer them hot? The Rockefeller ($80 per piece) come out golden and buttery. We wrote a whole piece on where to eat fresh oysters in Cancún.

The Japanese half: five rolls, no filler

Here's the honest part: we do not have a sixty-roll sushi menu. We have five, and each earns its spot. Plátano con Queso ($165) is the most Caribbean, with shrimp, eel sauce and toasted sesame. Camarón Tempura ($170) brings masago, cheese and avocado. Dos Atunes ($170) — avocado, chives and jalapeño — is the house favourite. Empanizado ($200) piles on two cheeses, crab and tamarind sauce for the crunch crowd. And Salmón ($200) finishes with spicy crab, avocado and fried leek. If sushi is why you're coming, we go deeper in where to eat sushi in downtown Cancún.

How it ends

Two desserts, no ceremony: fried plantain with jam, condensed milk and ice cream ($165), or crème brûlée ($165). After a table of cold, raw, citric things, warm sugar lands harder than you'd expect.

The chapter nobody expects: breakfast

Plenty of people find us as a seafood and sushi restaurant and never learn that we open the morning too. Every day from 7:00 am to 12:30 pm there's a breakfast menu served beside the pool: shrimp chilaquiles ($230), shakshuka ($215), hotcakes ($150), French toast ($195) and ten cold-pressed juices from $110. Essentially a second restaurant inside the same garden — we broke it down in where to have breakfast in downtown Cancún.

How to order at a seafood and sushi restaurant in Cancún

When the table is mixed — a raw-fish devotee, a sushi loyalist and someone who "doesn't really do fish" — order in layers, not by person:

• Open with oysters by the piece plus something universal, like guacamole, while everyone reads.
• Follow with one tostada each — the cheapest way to try four different things at once.
• Send one ceviche and one aguachile to the middle. First time? Make it the black one.
• Close with two shared rolls, one raw and one crunchy.
• Stagger the order instead of firing it all at once: raw dishes are best the second they land.

Want the dish-by-dish version with our recommendations? That's what to order at MERO 18.

What we're not — and where to go instead

Menu honesty: we are not a traditional Mexican marisquería, the kind with seafood broths, whole fried fish and loud midday botanas. If that's the craving, downtown Cancún has neighbourhood marisquerías that do it properly and deserve the visit. We're also not an encyclopedic sushi bar — if you want forty variations on a breaded roll, a dedicated sushi place will make you happier. What we do is the opposite of a catalogue: a short list of the day's product, handled by few hands, spoken in two languages.

The setting: a jungle hidden in downtown Cancún's historic heart

You step off the avenue, through a doorway, and the city noise simply stops: palms, striped shade sails, warm string lights and a cenote-style pool with a rock waterfall. It really is a jungle hidden in the historic centre of Cancún, and it's half the reason people come back. The other half — for anyone whose relationship with Caribbean heat is non-negotiable — is the glass-walled dining room with air conditioning, wrapped by that same garden: climate control without losing the view.

We live inside Mezcal Boutique Hotel, but the restaurant is open to everyone — you don't need to be a guest. We're steps from the ADO bus terminal, a five-minute walk from Parque de las Palapas, and roughly fifteen minutes by car from the Hotel Zone. On TripAdvisor we hold a 5.0 with a Travelers' Choice award and rank #20 of 1,380 restaurants in Cancún; on Google, 4.9. We mention it knowing those numbers get re-earned every service.

Come taste both halves

The only real way to understand a sea bar is to sit at one. Find us on Avenida Carlos Nader, in downtown Cancún, open straight through every day from 7:00 am to 11:00 pm. Bring the oyster person and the sushi person: for once, they won't have to negotiate.
