Oscars Burritos Mexican Grill

Amazing restaurant! I came here about 6 years ago and it is just as good now! Everyone serves your food with a smile and they genuinely look like they love making their burritos! And when you take the first bite of your burrito you understand,.these are the best burritos I have ever had. The ingredients are fresh the meat tastes so great, and you can make any burrito into a chimichanga! I would highly recommend this restaurant to anyone who is in the area!

Stopped at Oscars Burritos for a quick lunch break. It’s similar in style to a Chipotle, build-your-own fast casual, but with a more authentic feel. I went with a spicy chicken burrito and tortilla chips. They also have some signature burritos I wish I would have tried. The burrito was good. Portions size was good. Indoor seating had plenty of room but could use an update. Outdoor seating was also available. Parking across the street was not lined and a bit chaotic. Overall good experience.

If you’re in Boxborough and looking for a high-quality, local alternative to major chains, Oscar’s Burritos is an absolute must-visit. Located in a charming "farmhouse" setting right off Massachusetts Ave, this family-run gem consistently delivers fresh, flavorful Mexican food that truly stands out. The Blackened chicken is the best piece of meat I've ever fit inside of my mouth, and the service is incredibly fast and efficient. A special shout-out goes to the awesome cashier, Mr. Bling Bling, whose energy and style make the checkout process just as memorable as the meal. And don't forget about desert, the tres leches cake is to die for. 5/5

Steak burrito was great! This is a fast takeout place that offers seating, but I was very impressed with the quality of the food.

This is the best mexican option around by far. It is inexpensive, full of nutritious options, tasty, and the staff are all interesting and vibrant individuals. Watch out, this place has a strong base of local die hards, and during peak hours (11, 5) it can get slammed. For good reason. I have already been twice in the last two days and to be quite honest have not ruled out a 3rd day in a row. staff gives free drinks and sauces. A++ service and food
