Tandem Coffee in Portland: Which Location to Visit

If you mean the Tandem bakery, save 742 Congress Street. If you mean Tandem's East Bayside café and roastery, save 122 Anderson Street. Both are in Portland, Maine, but they are different stops with different opening schedules.

That small distinction can save an unnecessary trip across town. Here is how to choose the location that fits your morning, using Tandem's own location pages rather than treating the two addresses as interchangeable.

The two locations at a glance

Schedules checked September 22, 2026. Confirm special closures and holiday changes before travelling. The one-hour difference in opening time matters if you are planning an early start; the Sunday difference matters even more.

Choose Congress Street for the bakery

Tandem's Coffee + Bakery page identifies the Congress Street location as the bakery and lists indoor and outdoor seating. Its same-day online ordering window is 7:45–10:15 a.m., which is shorter than the café's opening hours.

If you want to order ahead, follow the ordering link from that page, choose what is actually offered and check the pickup instructions. The ordering window is not a guarantee that a particular pastry remains available. A saved screenshot of yesterday's menu is less useful than the current ordering page.

The bakery also states that it has no Wi-Fi. That makes a difference if you are choosing between meeting a friend for coffee and settling in for a work session. Do not build a remote-work plan around a connection the café does not provide.

For the bakery, use the official Congress Street page above. Our Tandem Coffee Roasters profile refers to the Anderson Street location.

Choose Anderson Street for the café and roastery

The Café + Roastery page lists espresso drinks, pour-overs, tea, pastry and retail coffee beans. The roastery operates on the same small campus, in a separate building from the café.

This is a different starting point for your day: an East Bayside coffee stop rather than the West End bakery address. If your main task is buying beans, check the café's retail selection. If you are coming for a particular bakery item, confirm it at the intended location rather than assuming both counters carry the same range.

The café's published schedule is Monday through Saturday. Do not transfer the bakery's seven-day schedule to Anderson Street when planning a Sunday outing.

Why the opening years sometimes get mixed up

Tandem's company history dates the original café and roastery to 2012, followed by the West End bakery in 2014. Those dates describe different locations. A reference to Tandem beginning in 2012 does not mean the Congress Street bakery opened that year.

For a visitor, the practical takeaway is simple: use the location name, street and current schedule together. When meeting someone, send the full address instead of only writing “Tandem.”

Build the rest of your morning around the right stop

Choose the coffee stop first, then look for another place in the same part of town. Our West End collection and Bayside collection help keep that choice organized. The broader cafés and bakeries directory is useful if neither schedule fits.

For accessibility, specific seating needs or a large group, ask the café directly. A statement that seating is available does not establish step-free access, a quiet room or an open table at the time you arrive.
