Eleven Winters, None of Them Closed

Ceres Street is the working end of the harbour — tugs, a fish pier, and the part of Portsmouth that carries on in February when the rest of it is a nice place you'd visit in August. We opened here in 2015 and have not closed for a single day since, including the two blizzards where we walked in.

That is the entire business model, stated plainly. In July we serve four hundred people a day and most of them we will never see again. From November to April we serve maybe ninety, and almost every one of them is somebody whose usual we know. The summer pays for the building; the winter is the reason anyone works here.

So the decisions all lean the same way. The chowder comes on in October, not June. The filter is free before nine when the boat crews are in. There is a broth on the stove all winter that we give away below freezing. None of that makes sense on a spreadsheet in August, and all of it is why there's still a queue in August.

  • Open every day since 2015, including two blizzards
  • Roughly 400 covers a day in July, 90 in February
  • Free filter refills before nine for the boat crews
  • Free broth below freezing, all winter
The Room

Four Things Worth Knowing About the Building

It is a small brick room on a cobbled street with a lot of weather outside it.

Six Seats Over the Water

A bar along the back window, cantilevered out over the Piscataqua. Best seats in Portsmouth and everybody knows it — but they're empty at seven in the morning, and a tug usually goes past around quarter to eight.

The Tide Board

A chalk board by the door with today's high and low water. Locals use it; visitors photograph it. High tide is when the window seats are genuinely spectacular and low tide is when you can see how the pilings work.

We Open in Storms

Nor'easters included. The street floods at the bottom occasionally and we've served coffee to people in waders. If the power goes we do filter on a camp stove, which has happened four times.

Dogs on the Cobbles

Not inside — it's twenty-eight seats and a working kitchen. There are two benches and a water bowl on the street side, and in summer that's where half the conversation happens anyway.

How the Queue Works

Four Things That Make It Shorter

In July the line goes up the cobbles and we're not going to pretend it doesn't. Here is how the regulars beat it.

1

Before Eight or After Two

The tour boat empties at one and the cruise shuttles run eleven to one. Between eight and two on a July weekday it is twenty minutes; either side of that it is four.

2

Order From the Street Window

The hatch on the Ceres Street side is coffee and pastry only, no seating, and it moves about three times faster. Most visitors don't notice it exists and every local uses it.

3

Know What You Want at the Door

Not a rule, just arithmetic — the menu is on the wall outside for exactly this reason. Thirty people each taking forty seconds to decide is the entire difference between a four-minute queue and a twenty-minute one.

4

In Winter, Just Walk In

November to April there is no queue at any hour and there are seats at the window. If you can choose when to visit Portsmouth, choose February — the town is better and so are we.

When to Come

A Year on Ceres Street

The same room does four completely different things depending on the month. This is an honest guide, including the part where we tell you to come in the off season.

1

May to September · Loud and Excellent

Lobster roll on, cold brew on, the street full, the window seats gone by nine. It's genuinely the best version of Portsmouth and you will queue for twenty minutes at lunchtime. Worth it once, and then come back in October.

2

October to November · The Good Secret

Chowder comes on the first of October. The tourists thin out, the light goes gold at four, and the room is full of people who live here. If we could only keep two months of the year, these are the two.

3

December to February · Ours

Ninety covers a day, all of them regulars, broth free below freezing, and a fire the building code lets us call a wood stove. Storms included. This is what the summer pays for and we like it best.

4

March to April · The Awkward Bit

Grey, muddy, chowder's still on but the lobster isn't yet. Nobody's finest month and we won't pretend otherwise — but the room is empty, the coffee is the same, and the whole harbour is yours.

Good to Know

Questions We Get Every Week

When is it quietest?

Before eight or after two in summer, and any hour at all from November to April. The tour boat empties at one and the cruise shuttles run eleven to one, which is the whole story of the July queue.

Can I get one of the window seats?

Not by asking — they're first come and there are six of them. In July they're taken by nine. In February they're empty at any hour, which is one of several reasons February is the right answer.

Is there parking?

Not on Ceres Street, which is cobbled and mostly for deliveries. The Bridge Street garage is a four-minute walk and free after seven in the evening. Everyone circles for ten minutes once and then never tries again.

Are you really open every day?

Every day since 2015 — no closures, no reduced winter hours, no shutting for a fortnight in January. Two blizzards we walked in. It's the thing we're proudest of and the reason half our regulars are regulars.

When is the chowder on?

October first to the end of April, without exception. People ask in August and the answer is always no. It's a cold-weather thing and serving it in July would make it a worse chowder and a worse restaurant.

Why is the lobster roll market price?

Because the price of lobster moves weekly and printing a number would mean either overcharging you in a good week or losing money in a bad one. Today's is on the board by the door and it's the same price for everyone.

Do you do a vegetarian option?

The smoked fish toast is the only non-veg item on the food menu besides chowder and the roll — everything in the bakery case, the soup on Wednesdays and the egg baps are vegetarian. Vegan is thinner and we'll say so rather than oversell it.

Can I get the beans you use?

Yes — twelve-ounce bags on the shelf, roasted across the bridge in Kittery on Tuesdays and here by Wednesday. $18, and we'll grind it for whatever you brew on if you tell us.

Genuinely, Come in February

The Best Month Here Is the One Nobody Books

Ninety covers instead of four hundred, the window seats free at any hour, chowder on, broth free below freezing, and the whole harbour to yourself. We'd rather tell you that than sell you a July queue.
