Today I gave this restaurant a try and the couple running the establishment were  very nice.  The food was fresh and the corn tortillas were perfect, soft and warm.  The al pastor was a bit dry and had some gristle, the carne asada was okay, the chicken taco was excellent.  I liked the chips and two different salsas offered.  Rounding out the dinner, the rice and beans were very good.  The horchata was heavenly and I regret not having got the largest size.  The restaurant is dated and lacks ambiance.  It's a good place to eat a quick lunch or dinner.  but I don't think you'd want to bring a date here.
Review Source:My mom and I wanted a real authentic Mexican dinner in the city. Since she was visiting from Ohio, I wanted to take her somewhere really different. I found this place just by searching on Yelp. We decided to dine in, which I wouldn't really suggest since it's pretty tiny and we were just about the only ones there.
My mom ordered the chicken fajitas and I ordered the Burrito Suizo. OH. MY. GOODNESS. Sooooo good!! I am so glad we came here. The prices were so cheap and the food was some of the best Mexican I have ever had. We also got the guacamole as an app and again, AMAZING!
I would certainly recommend this to anyone who loves them some Mexican food! However, I would recommend that you take out and not eat in! It's pretty plain inside and there was bit a basement smell. But in any case, insanely delicious Mexican food. Go try it out!!!
Wow I wanted a nice and juicy full of juice burrito with all the toppings mmmm mmm good not like quiznos ,but more meat to make me dance on my feet. Â So I was boggling my mind of what to eat on these cold chicago streets and I thought hmmm yes FAST BURRITO. I skipped in with my care bears jacket on and my jetsons shoes. I know my stomach was acting up not because I was hungry ,but for the fact I knew i had how do you say oh yea DA FARTS. I waited in line and all of sudden I was letting them GO rip,toot ,oh my goodness it was like a car backfiring. One after another. All of sudden the gentleman in front of me let's call him RONALD. " WHAT THE HELL YOU NEED TO STOP FARTING!!!. I was shocked and didn't pay attention ,but Ronald yelled maybe you need to use the potty. I went up anyways and put my order in for a big fat juicy BURRITO. As I was ordering RONALD yelled NO BEANS FOR THIS GUY NO BEANS! The cook was shocked and said what NO beans I said light on the beans for me cause of my tummy.
As I eat the juicy mouth watering fun of meat. I have to admit the volcano of noise came back and it was off to the bathroom. Luckly 20 mins later after sweats and praying to the big JC I was on my way. whooo what a trip.
No, this is not some knock-off Chipotle as the name sounds. Having been on a search for a good authentic Mexican restaurant in Chicago, I think I may have found it. No frills, no fuss, just some good freakin' tacos.
Portions are large, the meat is well-seasoned and juicy [side note: I hate that word], and the tacos hit the spot. We tried an assortment of pastor, chicken, and asada. While I always lean to chicken tacos, the pastor were the highlight, as were the chips with the freshly-made guac.
Friendly staff and owners, easy on the wallet, and super clean as well. Winner.
This is a little family owned restaurant suffering from poorly chosen name syndrome. The food is both hand and well made but the name implies a garbage fast food Mexican place that provides you Tabasco to spice up your burrito with. Had I not been killing time on the same block I would've never thought to give them a try. Â They seem like a nice couple and I'm glad I did.
The al pastor was very good, portions were solid, the chips were warm and I believe made fresh and the guacamole was delicious. Everything was well seasoned without being too salty.
It's a good little place just a bad name.
I think the name is very well chosen. I did not find anything special about their food, except that it is indeed as fast as any food you get in a taquerias.
The food is rather plain. Honestly, I have seen many far more better taquerias  in Chicago for the same price and in more expensive locations.
I like Mexican Food, plain and simple. Â mexican food is not afraid of a little spice...and I like SPICE!! Â Bring on the jalapeno's and RED HOT salsas.=D
I've had carry out twice from this little gem. Â Delicious.
My favs so far:
1. Â Tacos el pastor
2. Â Tacos asada
Honorable Mention: HOLY MOLEY GUACAMOLE!! The cook made it fresh on the spot. MUST TRY!! Slather it on your tacos. Â Add the green and red salsas and you have a mighty tasty authentic mexican experience.
Small mom and pops restaurant. Â Worth a try. Â If it tastes this good after a 20 min drive home, it must rock fresh off the grill!
The meat is tender and flavorful. Â
oh, I had Frontera Fresca (old orchard mall location) a few days..cringed at my taco el pastor and was like  "Yuck!" ...give me my Fast Burrito.
Truly outstanding Mexican food hidden on Irving park rd near kimball!  The tampiquena con 2 enchiladas and tacos asada were excellent.  The best was the  tacos and burritos al pastor/.  Order some guacamole and add it to your meals.  The guacamole was perfect.
The owners are super kind and the restaurant is very clean.
I just had lunch at frontera grill and dinner at xoco and this place was better than xoco and almost as good as frontera grill!
Authentic small Mexican restaurant, recently opened, run by nice people who deserve success in the future.
It's a little unfortunate that they chose the name "Fast Burrito", because it makes the place sound like some quite generic tacqueria.
Actually many things here are a cut above average. Clean, new, well-lit, with an open kitchen. The woman there was preparing licuados in a blender when not working on the entrees. Nicer plates and cutlery. Has table space for about 25 people.
Good salsas, not sure if they make them in-house but I assume that they do. Large menu, has some items which are specifically vegetarian. The enchiladas with mole were excellent. Â Very inexpensive prices, getting a very good value for the price. Â
Read the Spanish-language newspapers. Talked with the owner for a long time about reminiscences of my travels in Mexico. Then we watched the Mexico versus El Salvador World Cup soccer preliminary match on TV. Mexico won, and we had a grand old time shouting
"Goooooooolll !"
along with the overdramatic Mexican sportscasters.
