“ This place is always busy. Delicious tacos de lengua but $6 per taco is a bit much for me. Still I should say they fill the tacos with meat to the point that you could make a baby taco with all the meat you spill. Guacamole and chips never disappoint either. The lime included with each taco is always very juicy. The ladies working here are extremely fast and nice. A few tables to sit inside and a couple more outside. There's no music playing but it doesn't need it as all the noise from those working in the kitchen and the customers getting their orders keeps this place active. ”

“ This is a family favorite spot. Simple but quick, delicious, and great prices! This small, unassuming restaurant is co-located with a gas station. Very few tables inside (maybe 2 small ones) and a few more bigger ones back. Orders come out quick and are always correct. Chicken quesadillas are so flavorful, burritos are stiffed, quac is on point, and tres leches is a perfect finish. ”

“ I've been coming to Taco Bar in Gaithersburg since high school--over 20 years now--and it's still one of the best spots for authentic Mexican food in the area. The tacos are always fresh and flavorful, with generous portions and a great selection of meats. The lengua (beef tongue) is a must-try--tender, juicy, and packed with flavor. I also love their al pastor--perfectly seasoned with just the right balance of sweetness and spice. Their salsas add the perfect kick, and everything tastes homemade. Located right by the gas station, it's a hidden gem that never disappoints. There's outdoor seating if you want to enjoy your meal on-site, and you can also pick up beer and wine here, which is a nice bonus. Whether you're grabbing a quick bite or craving a late-night taco fix, this spot is always a solid choice! ”

“ Year later and this place still is crushing it. Definitely still king whenever I crave tacos. I love their loaded nachos! Make sure to try this place at least once! The ladies are super efficient and friendly. ”

“ My go to place for solid Mexican food. Anytime I crave a burrito or nachos, I always come to Taco Bar. The food and service is so so good.I have no complaints. I would recommend this place to anybody looking for an authentic and affordable Mexican place. My friends all know and love this place as well. A great togo spot. ”

“ A hidden gem in Gburg awesome tacos hidden in a gas station. I got the al pastor, langua, and shredded beef. All were good definitely utiliaze their taco bar. I got roja sauce which was perfect. Langua was a bit too chewy. This place is also beer and wine shop. Doesn't have many tables. It is no frills but great food. Service is good and the restaurant looks very clean. ”

“ What an amazing hidden gem!! It's so hard to find authentic tacos in the area that are not overly priced but you can find that at bar El Guero. Food 9/10: the tacos slapped! I had the steak, pastor and chorizo taco. My least favorite was the chorizo because it was a little dry. I also had the chips and guac and you can tell the guac was made fresh. Service 10/10: the staff was super friendly and the food was prompt. Ambiance: no rating because as you can see it's mostly a takeout restaurant. They're located right next to a gas station and they have a few tables outside. ”

“ My friend and I were feeling a bit hangry after walking the bucolic grounds at the nearby Glenstone Museum (https://www.yelp.com/biz/glenstone-potomac) and my handy Yelp app suggested the Taco Bar El Guero. TBH, I've had this place bookmarked for over 5 years, and as I was in the area, this was the perfect time to finally check this bookmark off my list. If there is almost one universal truism when it comes to food establishments connected or are near gas stations, the food is usually ah-mazing! Taco Bar El Guero is located behind a Shell station (although locals tell me this has been other branded gas stations in the past), so be forewarned that parking is limited. TIP - there is another smaller overflow parking off to the side when pulling in...just be on the lookout for it. Luckily, we were able to find a spot near the front door, and walking in, you can be forgiven if you think this is a liquor store, since there are rows of wine as well as several fridges with full beer displays. But walk in further, and you'll see the counter to order food. The menu is extensive, so my advice is to snap a pic, step off the side to review, and then order when ready...so as to not block the usual long line of patrons waiting. We decided on a trio of tacos (Lengua, beef short rib, and the bistec), as well as the beef asada platter. The tacos were HUGE and overflowing with meat. The condiments/toppings are simple: onions, cilantro, and lime off the side. A green salsa verde also accompanies all dishes. Previously I wasn't a fan of lengua, but their version was fatty and didn't have an off putting "gamey" flavor with excellent seasoning. Bistec was also good, but a bit on the dry side. The short rib was the best of the trio. Tender braised beef was melt in the mouth tender. There was plenty of meat to use the extra corn tortillas to make 2 or 3 tacos. We were already getting full, but sampled the beef asada platter. For $11 (at the time of this review), it's a bargain. Three lean pieces of beef are seasoned and cooked on the flat top with a nice sear. When hot, the meat was tender enough to slice with a plastic knife. Take a few strips and stuff a tortilla with the beans/rice/lettuce/tomato, and you have a great build your own taco. With tax and a Jarritos soda, the total came out to approximately $26; I'd say this classifies as a cheap eat for two ppl especially since there were plenty of leftovers for the next day. If this place wasn't an hour away, I would for sure by stopping by here weekly. IMHO, Taco Bar El Guero is one of the better taquerias in the entire DMV. ”

“ Was NOT prepared to have tacos THAT good out of a gas station, but here we are. I visited the Taco Bar with a friend who's a longtime patron. He assured me the tacos were official and he was 100% correct! The Taco Bar is to the back of a gas station, past refrigerated beers, wines, and other beverages. It's pretty unassuming, just a counter and a large menu hanging overhead. It takes up very little space and there are about 4 small tables nearby that can seat 2. I ordered the "Pick 2" platter option. I went with 2 steak tacos and the platter came with sides of rice and beans, and a drink. We sat outside on a fairly large patio with 4-5 tables with chairs. It was a nice day, so totally worth it! Our food was delivered and we dug in, and OMG! Those steak tacos were fuego!!! Well seasoned, moist, and no skimping on toppings. The beans were much the same, super tasty and great over the rice. I was wholly pleased and filled up by my meal. And the prices were super reasonable/affordable. Next time I'm in the area, I'm definitely returning here! ”
