    Open to 3am, amazing option to hang out with friends after work and get a bite to eat. I recommend the chicken birria tacos.

    The food was really good and had really nice proportion. When I went in I got freshly cooked meat for my bowl and even with double meat it was only like $15 :). the only thing I'd say I didn't like was that my steak was a little over cooked, but other then that it was really good.

    Unbelievable food and an amazing experience every single time. Guacamole Island Mexican Grill has quickly become one of my absolute favorite places to eat. The food is always fresh, flavorful, and made with care. Everything I’ve tried has been delicious, and you can truly taste the quality in every bite. The atmosphere is welcoming, the restaurant is very clean, and the staff is incredibly friendly and attentive. What makes this place even more special is the owners and their family. They are genuinely kind, hardworking people who make you feel appreciated every time you walk through the door. You can tell they truly care about their customers and take pride in what they do. The portions are great, the prices are affordable, and the overall experience keeps you coming back again and again. Highly recommend to anyone looking for authentic, delicious food and a place that truly feels welcoming. This place deserves all the support and success coming to them!

    Kept passing this place for a while. Figured we would give it a shot, and it unfortunately disappointed. The girls at the front desk were efficient with taking the orders. But we waited an hour for 2 orders of tacos which in a customers eyes in unacceptable. With only 2 other customers in the whole place. Staffing seemed to be an issue with only two people running the entire business. Not saying it was the staff issue but more of a management issue. The food was bland, the tortillas tasted stale. I’d prefer another business.

    I was not impressed with the food at all. The steak was chewy. The shrimp was overcooked. The rice was bland. Also, when I walked in to order, the most vulgar and inappropriate music was playing. I would never bring my family here just based on that. I get if of no one was there and they were playing it for themselves, but it it should have been switched after I walked in. Pretty disappointing.
