New Main Street eatery features authentic Mexican cuisine

Former Waltham residents Ramiro and Raquel Marin are the proud owners of a new Mexican restaurant across from Waltham Common.

Monarca Taqueria at 663 Main St. is now open for lunch and dinner and offers such options as traditional Mexican soups, tacos, burritos, quesadillas, bowls, seafood and ceviche along with margaritas and other beverages.

Its space is the former location of The Elephant Walk and Gustazo, the latter of which moved to Moody Street in 2022.

All food at Monarca Taqueria Waltham is prepared on-site and cooked from scratch using fresh ingredients — and the word is getting around. Since the grand opening on Feb. 7, Monarca Taqueria has had several rave reviews posted on social media sites including Google and Yelp. Some diners even come two and three times a week to try different items on the menu, the owners said. 

“Atmosphere was on point from the moment I arrived. Food did not take long to arrive and was delicious. Seriously, the best Birria in Waltham,” said Dom R. in one review. 

“I have to say my wife and I loved it! We got tacos. The steak tacos were outstanding and the steak had so much flavor,” said Darren412 in another.

The Marins lived in Waltham for more than 25 years and now reside in Milford where they opened their first Monarca location four years ago.

“We love the community. My kids were brought up here, and they all went to Waltham schools,” Ramiro Marin said. “We’re just glad to be back and get such a warm welcome.”
