Sunday lunch may have a butter-versus-mayo situation on its hands.

An AllEvents listing attributed to Cousins Maine Lobster advertises a San Elijo Hills appearance on Sunday, November 15, 2026, from noon–7 p.m.

The listed address is 1215 San Elijo Road, San Marcos. The Lost Abbey identifies that location as The Sanctuary tasting room.

The appearance remains advertised rather than independently confirmed through an accessible original organizer announcement or venue schedule. Check before heading over.

First, Find the Right Abbey

The promotion calls the destination The Lost Abbey Brewery in San Elijo Hills. The company’s name for this location is The Sanctuary.

The address is your friend here. Arriving hungry at the wrong tasting room would be an unnecessarily complicated appetizer.

According to The Lost Abbey, The Sanctuary opened in November 2019 and features rotating food trucks Wednesday–Sunday.

Its official page also lists outdoor seating and a dog-friendly policy.

That gives the advertised visit a neighborhood connection: a visiting food truck joining a tasting room’s established rotation.

For Vista and San Marcos readers planning the outing, the useful details are the exact location, the advertised service window and a final schedule check.

The Roll Call

Cousins’ classic Maine and Connecticut rolls both feature Maine lobster. The difference is what happens before they reach your hands.

The company describes its Maine roll as chilled lobster with mayonnaise on a New England roll, accompanied by a lemon wedge.

The Connecticut roll takes the warm route, with butter and lemon on a New England roll.

One goes chilled with mayo. One goes warm with butter. That’s the ordering distinction worth remembering.

The company also advertises a garlic butter lobster roll.

The supplied event listing names all three styles, plus lobster tacos, quesadillas, grilled cheese and tots. The event-specific menu has not been independently confirmed.

The announcement does not include prices, either. Check the current selection and cost before making promises to the entire group.

Your Points Can Follow You to the Window

The listing advertises ordering at the truck or through the Cousins Maine Lobster app.

The company’s official instructions confirm mobile ordering, payment and designated pickup times at locations accepting app orders.

Prefer ordering in person? Cousins says a team member can scan the app’s Loyalty Card QR code to attach that purchase to your rewards account.

You can order at the window without necessarily leaving the points behind.

The event listing says the truck will be cashless, accepting credit, debit and Apple Pay. It also warns that mobile ordering may be limited.

Those event-specific instructions still need confirmation.

Keep the Plan Simple

The promotion calls this an annual lobster fix.

A recurring yearly San Elijo Hills appearance has not been established.

There’s enough to consider without adding a countdown: verify the stop, check the prices and choose your roll.

Then settle the butter-versus-mayo debate over lunch.
