Don't be me, don't go on a Friday night and try to get street parking. Plus parking in the back would have been way easier because they have a desk for seating right off the back. I like the layout, it's open, but not open. Really cool. My wife and I sat in a booth that was tucked in by the kitchen. It was perfect. You could hear the fun and conversations people were having, but you had your own spot. We liked it :) I looked at the menu before we went so I knew what I was in for and I was all for it. I didn't tell my wife but knew she would love it, so I padded in some extra time for her to look. Look at the menu before you go, just glance, it's big..but not crazy. The food, awesome! Lots of it. I had a chimi because that's what I do lol. (Long story, my mom loved them...so no matter how amazing the menu...it's what I do. Sorry Yelp lol) But the food was amazing, and hot, and quicker than we would have expected. So all the things were perfect for us. Price was just fine. You can go whatever direction with the menu your pocket desires really. We added another entre and split it, so we went over what we normally do. But hey, date night :) Overall we loved it, reminded us of Carlos O Kelley's in Cedar Rapids, Iowa. We lived at that place. This place is almost it's twin and we are thrilled. And, which shouldn't be a side note, the staff was amazing. Didn't press us, and was just really nice. Thanks everyone, excited to come back!

From sitting down to getting our food was less than five minutes. The food was extremely fair priced. However, I cannot call it authentic. The flour tortillas were clearly purchased at the Walmart supercenter. The El Cabrón burrito I ordered was chopped up chicken breast inside a cold flour tortilla, smothered in queso. The beans were very watery and the rice was very good. Once I mix the beans and rice together, the beans seem to have a little flavor. Did I mention the burrito only had chicken inside nothing else? We also get the mango tacos, which was a mini version of the El Cabron burrito with some mango juice poured over the meat. It was fast. It was an expensive and it was filling. It did not remind me of Mexico. When we ordered the mango tacos, I expected some kind of mango chutney on the chicken, unfortunately, it was like someone opened a can of ocean spray and pour it on the meat. We will return, but it was boring.

My hubby heard great things…read more It was "meh". They have steak but don't offer steak fajitas...... Chicken was a little over cooked, and the rice had ZERO flavor. Also- they gave me a DOLLOP of sour cream for 3 tortillas. I also agreed that if you have a business don't skimp of the important things-! STREET CORN HAS CHAR!!!!!! It should NEVER be canned corn- I mean, c'mon. But he did say it was decent. He ordered the Sunday special- and he didn't like it, at all.... He said the meat was all fat- No meat in it. And the "consommé" had zero flavor, and was oily. The best thing I ate was my daughters French fries....sadly. The margarita was ok. Not the best.... Not in a hurry to go back. But had to try it.

I recently ordered takeout from Tres Caminos and was very unhappy with the food, service and condition of the restaurant. My chicken taco salad was dismal: the chicken was shredded and looked and tasted dry. It was a very small serving, and the bill was More than $12.00 - more than posted on the online menu. The other item, enchiladas verdes, was a tiny serving, only one enchilada, not three as listed on the online menu. Why so stingy?? The total bill was $48.00 - wrong price and way overcharged! No beverage, no side sauces, nada! The fellow at the counter offered no explanation, and quickly looked away. The whole place was a mess - old and tired looking.
