Eating authentically prepared food lets you taste the very essence of a country and draws far fewer angry glares than chewing on its national flag. Get in touch with Mexican culture with today's Groupon: for $10, you get $20 worth of authentic Mexican cuisine at Si Senor! Real Mexican Food in Boulder.

Si Senor skillfully serves a menu abundant with delectable Mexican fare. The Si Senor breakfast sates hungers built while squeezing full-size bricks into legos with two eggs, home fries, two tortillas, green chili, and a choice of crispy bacon or spicy chorizo ($7.25). Lunch seekers can munch on the burrito sampler plate, a medley including four 6-inch burritos ($9.75), and the make-your-own combo allows diners to mix and match items to create a dream team of hunger-conquering eats ($9.95). Cultures collide with the mexican hamburger, a flour tortilla filled with hamburger steak and beans strewn with cheese, lettuce, and tomato and served with rice ($8.75). A range of kid-friendly eats ($4.95) is also available to keep bored tots from starting careers in commercial real estate.

Wet your whistle with items from the extensive drink menu while relaxing in the colorful and cozy indoor lounge, or make your way to the outdoor patio to complement your meal with fresh air. On Wednesdays, musicians sashay into the eatery to soundtrack diners' conversations or their attempts to make conversation happen between two lonely, uneaten burritos.
