CHICAGO (CBS) — Calling all burrito lovers! Dos Toros Taqueria, a New York-based mission-style burrito chain, opened a restaurant in the Loop on Monday.

This is Dos Toros’ first location outside of New York, and you better believe Chicago came hungry.

Set to open at 1 p.m., people started lining up outside the new two-story, 4,000-sq. ft. location — 1 N. Dearborn St. — around 11 a.m. Monday morning. The line quickly stretched to one city block long.

As part of their grand opening, Dos Toros is celebrating the occasion with $1 Burrito Day. That’s right.

The glorious event allows those to taste-test any of Dos Toros’ meals, including burritos, salads or platos, quesadillas, or two tacos for just one dollar from 11:30 a.m. to 2:30 p.m. and from 5:00 p.m. to 8:00 p.m. Oh, and, because it’s important, guacamole is included for Monday’s promotion. You know what that means — no extra charge.

As if $1 burritos isn’t persuasive enough, Dos Toros also plans to donate one meal to the Greater Chicago Food Depository and the Food Bank for New York City for every photo posted on social media using the hashtag #DosTorosChi during the grand opening celebration.

Now, let’s get down to business: The menu.

In addition to your choice of meat — grilled chicken, grilled steak or braised pork — Dos Toros’ burritos feature melted Monterey Jack cheese, rice, black or pinto beans, veggies, salsa, sour cream and a choice of either smokey, Verde or habanero hot sauce. You can add guac for a buck.

Only their farro and flour tortillas (for burritos and quesadillas) contain gluten; everything else is gluten free. Furthermore, everything they offer is vegan, except for their meats, cheese and sour cream.

This new restaurant on the block will surely give Chicago something to taco bout’ (we are not apologizing for that), but, when will the inevitable Chipotle comparisons begin?
