McDonald’s fires back in McGrath Highway sign war

STEVE ANNEAR/GLOBE STAFF

A Somerville McDonald’s has fired back at Sav-Mor Liquors, which earlier this month began a playful sign war between the two McGrath Highway establishments, centered on the culinary blockbuster known as the Egg McMuffin.

This time McDonald’s is warning: “Sav Mor, You Ain’t Seen McMuffin Yet.”

The feud began when McDonald’s advertised “2 Egg Muffin [for $5].”

Sav-Mor, known for using humor in its signs, responded, “3 Egg Muffin [for] $4.”

“Your move, McDonald’s,” Sav-Mor’s sign said.

“When we saw the story and the sign, it was a no-brainer to respond,” said McDonald’s spokeswoman Lindsay Wallin. “We have done similar [things] in another location on Route 1 in Saugus. I’ve always admired Sav-Mor’s creative messages and we are happy to be included!”
