The G20 branch on Rue des Petits Hôtels
Supermarche G20 is a branch of the G20 chain, sitting on Rue des Petits Hôtels in the Canal Saint-Martin neighbourhood of Paris. What sets this one apart for a visitor is its position: it is the branch you reach from Château d'Eau station, on a street in the 10e rather than a counter inside a market hall.
The hours are the practical reason to keep it in mind. Doors open at 7:30 am Monday through Saturday, so it works for an early start before the city's cafés get going, and the 9 pm close covers a late errand on the way back. Sunday is the exception in a good way: 9 am to 8 pm, when plenty of other food shops in Paris are shut.
Spending lands in the €15 to €40 range for a basket, which puts it in everyday supermarket territory rather than specialty-shop prices. Come with a list and a rough budget and it behaves like any well-run neighbourhood supermarket: you fill the basket, you pay, you leave.
This is a small-format city branch, so treat it as a place to solve a need rather than to browse. If you want a market hall or a single-item specialty shop, the covered market and the small shops around Canal Saint-Martin are the better detour; this branch is the one that is open when you need it.
What to look for
7:30 am opening, Monday to Saturday
The doors open at 7:30 am six days a week, which makes it usable before most of the neighbourhood has started its day.
Sunday, 9 am to 8 pm
Sunday hours run from 9 am to 8 pm, so a Sunday errand does not have to be squeezed into a Saturday.
Rue des Petits Hôtels, Canal Saint-Martin
The shop sits on Rue des Petits Hôtels in the Canal Saint-Martin neighbourhood, with Château d'Eau station serving the area.
Who is this for
This suits a traveller staying in or near Canal Saint-Martin who needs a supermarket open early, since the doors are open from 7:30 am on weekdays. It also works for someone whose Sunday in Paris needs a food shop, with hours from 9 am to 8 pm when other places may be shut. And it fits a visitor keeping to a modest budget, with a basket typically costing €15 to €40.
If you want to browse and taste rather than tick off a shopping list, the covered Saint-Quentin market a minute away gives you a market hall with artisan cheeses, pastries and seafood instead of a supermarket aisle. Marché couvert Saint-Quentin.
The verdict
This is a small city supermarket branch rather than a market hall or a specialty shop, so it will not give you the browsing detour of the covered market a minute away, but it is open early, open on Sunday, and priced for an everyday basket of €15 to €40.
