I have been to Oscar's many times now, and the food and service is great. The food is always fresh, tastes great, and prices are affordable. The dining room is large, and there is an outdoor seating area. Sometimes service is slow, but that's because it's usually just Oscar or his son (?) preparing meals. As a few others have noted, the location is a bit strange -- it's in the barn-style building in front of Nashoba Valley Olympia skating rink, and the building is shared by an Ice Cream stand (not part of Oscar's) and a Garden Center (also not part of Oscar's). There is plenty of parking. read more

I want to like this place, I really do. Some of my coworkers love it so I keep going back to try again. No matter how many times I say no sour cream or no guac, I always get it on my taco salad! If you try to go around noon, forget it. It is too busy. Forget trying to call in an order too. You have to repeat yourself a million times and inevitably, your order is still wrong. But, so many people think it is great! So there must be something great about it that I just do not get. read more

This is one of those restaurants that you like to support because you know it is family owned and they obviously put their heart and soul into it. They also make one heck of a burrito. Located adjacent to a hockey rink and garden center, set back from the road, I was skeptical if it would survive for long after it opened. But now that I have tried it, I. can say that it is likely here to stay. The food was very good, the dining area is clean and simple ( I got the impression that many do take out here) and the cost was very reasonable. There is a good selection of meats and toppings and for those non burrito fans, do not pass it up. They also have salads and fajitas as well as plates. Kids always like quesadillas in my experience. I had the blackened Cajun chicken burrito and enjoyed it. The medium size was enough for me. Emphasis was certainly on the Cajun. The spice was significant but enjoyable. Gluten Free folk can have the corn tortillas, tacos, and nachos. If in a Mexican mood in the Acton Boxboro area, certainly check out Oscars. In the summertime, they have an ice cream shop there to satisfy the sweet tooth too! You can't go wrong. read more

Best burritos I have had this side of Boston.... My favorite is the Blackened Cajun Chicken burrito.....I have tried other burritos, all are really good...I have also tried the chimichanga option where you can turn any burrito to a chimichanga, which is also super tasty.....my go to place for lunch...... read more

Oscar's Burritos - Mexican Near Me - Boxborough, Massachusetts

Freshly prepared food pulled together quickly. We ate in the spacious dining room and the friendly staff brought our meals over as soon as they finished preparing them. Chicken pesto burrito had a multitude of flavors that burst through and the chicken fajita plate was delicious, although you might need to ask for extra wraps, as there is no way the fillings on the plate would fit in the 2 small tacos they provided. Not a complaint though - we will be back! read more

Best authentic mexican burritos in the area!! Full of flavor, several options to choose from, great takeout experience, highly recommend checking them out! read more

Finally went in today.... Blown away, first, I am a fan of bueno y sano, (although the Amherst one is really the best location.) But,Oscar's is going to take the crowd going forward. If you're a fan of Anna's Taqueria, then this will.be a pleasant surprise, very similar set up & quality. I will be back many many times! read more

Straight up great burrito. It was a chicken pesto and I enjoyed the flavor twist. It was in an interesting location within a garden center. Not the kind of place for a sit down experience, but perfect for a quick lunch. Service was quick and the ingredient quality was definitely palatable. Will go again if in the area. read more

Stopped by Oscar's for lunch a couple of days ago while visiting the area. I ordered a medium Hot and Spicy Cowboy burrito and it was very filling, with generous portions of fresh ingredients. Very tasty! The only critique I have, as a chili head and spice lover, the burrito was rather mild. So the hot and spicy description felt somewhat misleading. Next time I'll order a side of salsa and add on fresh jalapeños, which are both on the menu. I'll definitely stop in again whenever I'm in the area. read more

Hidden Gem! Oscar runs a wonderful business and the line moves extremely fast. One of the few "destination" spots for me that I will travel 20 minutes each way to eat(while passing chipotle & Moe's). Get the blackened chicken burrito, very unique flavor. read more

Cool spot... Service was super fast, food was great. Best burrito I've had in a long time. Moved to Massachusetts from California and is used to Mexican food everywhere, there's not too many authentic Mexican spots here on the east coast.. I got the Chipotle BBQ steak burrito and the portabello quesadilla.. both was really good. I will definitely be back again read more

Holy burritos Bat Man! Without a doubt Oscar has burrito making skills. Big, fat, juicy, and full of deliciousness. Nachos were bueno. Taco salad was bueno. Only bad things is there's no cervezas. I will definitely be back to gorge on more mexican yumminess. Gracias Oscar para una deliciosa comida. read more

Oscars is the kind of place that makes you smile I really enjoyed their burritos I ordered the chipotle steak barbecue burrito and let me tell you it was delicious the authenticity of Oscars really shines through they know how to make a burrito it's not the typical middle of the mall chipotle process junk!!! Oscars is the real deal they take care of their customers to the best of their ability. the flavors the flavors the flavors One bite and I was hooked absolutely hooked like a fish on the line I couldn't believe it was I actually eating a authentic burrito on the East Coast the answer was yes Oscars really really has done it they have truly mastered the craft of the burrito I felt like I was back in Guadalajara sitting at my Pepito's table enjoying one of my Nina's fresh burritos I am just so happy to have discovered this place I will come back here every single time I am in the Acton Boxborough area I cannot recommend any restaurant more than Oscars burritos read more

Oscar's Burritos - Mexican Near Me - Boxborough, Massachusetts

This place is pretty good the burritos are excellent the enchiladas are okay and the tacos are ok. What disappointed me the most is I called in a large order for work and they said it would be 20 minutes before my food was ready to pick up. I showed up 20 minutes later and they had not even started preparing our food. I had to wait for the line of customers to be served before they started getting my order ready!!!!! What's the point of calling in food if this is how they handle your order. Ridiculous!!! 45 minutes later I finally got our food. This place is ridiculously understaffed and the owner is obviously too overwhelmed to take care of his customers. read more

Food super tasty: tacos, burritos, dinners, whatever. Super tasty. However, the guy at the cash register has a perennial attitude and is not nice, nor customer service friendly. Literally has been the same pisser every time I've been in. Doesn't smile, rushes you, rude .... I mean, he just doesn't seem like he really wants to work there. And though super tasty, compared to Huipil or Anna's taqueria, you don't get nearly as much meat in the tacos as those places... kind of skimpy with the meat. They rather load you up with lettuce, tomato, pico, and everything else..... put more meat! read more

Excellent meal, you can tell they take pride the establishment was clean, bright and spacious. The owners run the restaurant and immediately make you feel welcome. I and a friend ordered a chicken, pork burritos and a tortilla soups which were delicious and warm. You could imagine my delight when the weather outside was 12 Degrees Celsius. I recommend this place! read more

I get a spicy chicken burrito when I go here and it is sooo good! I also like the atmosphere and the people who work here are very nice. I would recommend it if you like flavorful burritos! Better than chipotle in my opinion (I like the chicken better) read more

This place is excellent. It's ruined Chipotle and Bueno y Sano for me. Blackened chicken is amazing. Outdoor seating is breezy and nice. My daughter loves the mini quesadilla. read more

We really enjoyed Oscar's Burritos! The location is definitely unique, but we found it charming. And let's be honest, if the food feeds your soul, who cares about location! Our burritos were excellent, and I love that I could choose the size (medium or large). And kids are well cared for--they have little plates for kids' meals, which is awesome, because sometimes basket meals can be tricky for two year olds. We found the staff friendly and quick, and we'll definitely be back! read more

I wish I could actually review the food, but I didn't get that far. I walked in to a line of 5 or 6 people waiting to order and another 5 or 6 people waiting to pick up call ahead orders. The phone continued to ring with new orders. For 20 minutes, I waited in line to order, the line barely progressing because the staff were prioritizing the call ahead orders and ignoring the in person orders. All of people waiting to pick up had gotten their orders and new patrons rotated in, all receiving their orders and leaving. After 20 minutes, I gave up and left. Such a poorly run operation, very disappointing. read more

Solid place for some good Mexican food. Prices are a bit high for the quantity of food you get but it's good food. Stay away from the nachos though because they are the type of nachos that you can microwave yourself at home. read more

My wife and I moved from CA to MA four years ago. Having grown up in the Bay Area, I was spoiled with good burrito spots all around me. I'm still on the quest for a burrito joint on the East Coast that comes close to matching the West Coast in terms of deliciousness but I will say that this place is one of the better places around outside of the Boston/Cambridge area. The green salsa is tremendous. It makes the burrito. The steak burrito I had was a little dry inside but the salsa turned the meal into an enjoyable experience. Bonus points for a very friendly staff and the fact that this place is located inside a Garden Center. They also have a large menu with a number of specials. I will definitely be returning again soon. read more

Best place for burritos west of Boston. And they nail the spice levels. Acton is lucky to have this gem.

Love the taco salad supreme with portobello mushrooms! Our go to Mexican place. Wish they would hold off terminal cleaning until after they close. read more

This restraint is very good if you like spicy food and are a meat eater. For me who likes both this place is amazing and I really recommend it. If you are like my mother ( a vegetarian) your burrito is a little lacking. Especially because most of it is rice. If you don't like spicy food the meat can be bland. There sweet spot though is there spicy meats. Get that on a burritos and all is well. I will worn you that when they say spicy, the mean it. There Guacamole is very fresh and very good. Good place for lunch and Dinner. read more

I was worried I would be stuck with the food at my hotel while traveling for work, so when I found this place in the yelp app, I was eager to try it. The charred Cajun chicken burrito and papas Fritas were exactly what I love: spicy and savory. This little town is so lucky to have a place like this. read more

Went here for lunch today. It wasn't busy at all. My husband and I were the only ones there and we were there around noon. Service was fast. Prices were reasonable. I got the chicken taco salad. Everything was fresh and delicious. The taco bowl was crunch and delicious. I would consider going here again. read more

Finally a great Mexican restaurant, the food is delicious, the place is clean and nice and the service is fast and great. Certainly one of my favorite and will be back soon as I want to try everything on their menu. LOVE IT! read more

Great Authentic Korean food. We have been regular customers For many years. The food is consistent and delicious.

Really tasty! This is our go to spot for Mexican in the area. The Mexican chopped salad is a must. It's a great balance of flavor and crunch. The burritos are super yummy and filling. Our kids love the quesadillas. I've never had a bad experience here. Fast, good service too. read more

Love this place! We only had an issue once and we couldn't be upset over it really - they did red sauce instead of green sauce and forgot a couple items. They're nice and pretty stinking fast. Ate in twice and sometimes it's hard to get seats because they're so busy. read more

We stopped here on a long road trip with our toddler and dog. This place was nice because it was quiet and our daughter could stretch her legs a bit. We could also sit outside with our dog. Food was above average but not super authentic mex. You're going to get a decent and above average meal particularly if you want low key and easy. read more

Stopped here today and had some great burritos. Casual atmosphere with great food. Can't wait to come back when the ice cream is open too!

Hidden gem. Love the chicken soft tacos. Usually not too busy when I go but worth a try as tue foos definitely seems authentic and fresh.

I had the blackened Cajun chicken burrito and it has to be about the best burrito I've ever eaten. The fries were soft and oily and not the best. read more

Best burritos in Massachusetts! Must try the chicken pesto and the blackened Cajun chicken!

Places you don't expect to find good, affordable Mexican food: A former garden center next to an ice rink in exurban Boxborough. You'd be wrong though. Oscar's serves a surprisingly varied menu. I expected it to be a local version of chipotle, but they have more protein options, more inventive specialty burritos, salads, tacos, and even a few entrees. The food is simple, but very tasty. Close enough to 495 that you should stop by if passing through and looking for a quick lunch. read more

This a well run tasty option where few exist. They do great self-serve catering too!

After reading all of the positive reviews on yelp we decided to visit the spot for lunch. Unfortunately, upon arrival I was immediately put off by the fact that the restaurant was completely empty, and as quiet as a tomb, at 1:00 in the afternoon. Isn't that lunch time? We were greeted by the stares of 3 people behind the counter, no "hello" or "how can we help you" at all. I ordered a beef brisket burrito and a cup of chicken tortilla soup. My partner ordered a taco salad of sorts. The soup was delicious, although served with a plastic soup spoon that cut the corners of my mouth (Which was another odd thing about this place, some of our items were served on beautiful and colorful dinnerware, while others were served in plastic baskets with plastic utensils). My burrito was absolutely the blandest thing I have ever eaten in my life. I saw them put beef brisket on it, but found it difficult to locate any evidence of beef brisket as I ate it. It was like I was eating beans and rice wrapped in soggy flour tortilla (which came out of a bag, it wasn't homemade). The tortilla was so soggy it kept sticking to the foil it was wrapped in. It was very disappointing. My partner's salad was smaller than I expected it to be, but he said it was delicious. Prices were a bit high for what we received. You can get a much better burrito at Chipotle's, which isn't saying much. I would not revisit this restaurant. read more
