The smell of beef fills the air. The sound of sizzling burgers mixes with laughter and the general hum of student life. It is Sunday evening in The Den and Esteban’s is in full swing. While known for its tacos and other Mexican food, Esteban’s has been branching out into a new food. Every Sunday from 7-9 p.m., Esteban’s changes up their regular menu to serve an American classic meal: Angus cheeseburgers and curly fries.

Students have the option of a single patty or double patty. The burger comes with pepper jack, American or cheddar cheese. Students can customize their order with mushrooms, bacon, lettuce, tomatoes and onions. Burgers are available as a standalone order, a combo, which comes with curly fries and a drink, or a large combo, which comes with a larger serving of curly fries and a large drink.

“[The burger] reminds me of Five Guys,” said junior child development major Mariah White.

When The Den was first renovated, Esteban’s was a burger shop. Since then, the shop has offered a wide variety of food, including Chinese, a deli and the well-beloved taco shop. “Every couple years, [we’ll] change it into something else,” said Lisa Sargent, the location manager of Esteban’s. Esteban’s has been having pop-ups, temporary changes in menu, for various kinds of foods to see what students would be interested in if Esteban’s change permanently again.

Esteban’s has offered a variety of pop-ups this semester including burgers, crepes and poke bowls. Different pop-ups received different receptions from the student body. Crepes almost doubled Esteban’s regular customer base whereas poke bowls weren’t well-received. Although Esteban’s has done popups in the past, they’ve never offered this many pop-ups in a single semester. “Just because everybody’s so isolated,” Sargent said, “they need a little more variety, something to change it up.”

“It’s really cool having the burgers, doing something new,” said Esteban’s worker William Kozik. “It’s definitely different, but it’s fun.”

“Come and see the burger boys in action,” freshman Esteban’s worker William Green said.

Senior journalism and mass communication major Seth Johnson sampled the burgers twice. Seth first got a burger because the line for Papa Johns was so long. “[The burger] was really good,” Johnson said.

Johnson enjoyed his burger so much that he went back a different week and ordered the burger again. The first week he had the double angus patty and the second week he had the single patty. “Get them,” Johnson said. “They’re good . . . you have 150 Bruins Bucks. You might as well make [them] count.”

Anyone wishing to taste one of Esteban’s burgers should head to The Den on a Sunday night, from 7-9 p.m.
