Amazing food and excellent customer service!
The food was absolutely delicious and freshly made. The loaded nachos were packed with flavor—perfectly seasoned meat, melted cheese, fresh toppings, and just the right amount of sauce. The wings were crispy, juicy, and coated in a rich, flavorful sauce that tasted incredible.

On top of that, the customer service was outstanding. The staff was friendly, attentive, and made sure everything was just right. Great portions, great taste, and a welcoming experience overall. I’ll definitely be coming back and highly recommend this place!
Thank you NABIHA

I honestly disagree with the negative reviews. This place has some of the best food around—hands down. The quality is noticeably better than other Mexican halal spots in Suffolk. If you care about real flavor and quality ingredients, it’s definitely worth stopping by.

Just had an absolutely amazing cheeseburger! Seriously, it was perfectly cooked, super juicy, and the cheese was melted just right. Everything about it hit the spot. Definitely a must-try if you’re looking for a top-notch burger experience!

I had an amazing experience at Guac Island! The place has a really great vibe — clean, welcoming, and perfect for hanging out with friends or grabbing a quick bite. The food was fresh, flavorful, and you can really tell they use quality ingredients. Their guacamole is definitely a highlight — fresh, creamy, and perfectly seasoned.

The staff was friendly and the service was quick, which made the whole experience even better. Everything from the presentation to the taste felt well thought out. Whether you’re craving Mexican-style food, burritos, bowls, or just some really good guac, this place is absolutely worth visiting.

Overall, Guac Island is a fantastic spot with great food, great service, and a chill atmosphere. I’ll definitely be coming back!

Visited for a quick dinner and I was so happy I did. The birria (steak) tacos were so delicious by itself but the consume brought it up to a whole new level. They did not skimp on the meat filling and the broth had alot of beef in it as well. My daughter had the regular steak tacos with fixings and the steak was also tender and delicious. The staff were super friendly and accommodating. They made you feel welcomed and stopped by to make sure everything was good. The prices are reasonable for what you get and it is a good sized portion.
Parking is tight, there is a small shopping center across the road with ample spaces.
There is a bathroom on-site. Conveniently located on Portion Road when running errands to stop by for a quick lunch or dinner. I’ll be back to try some other items on the menu. 5 star service.

These gotta be fake reviews, the place was empty. We waited 30 minutes for a steak quesadilla with “special sauce” and a cheese burger meal (comes with fries and a drink)

I received a chicken quesadilla and no sauce, my coworker ordered a burger with fries and got 5 fries stuffed into a small container lmaooo not even lying. We just got back to our place of work and this review had to be done.

Concept is cool, the one guy taking orders is clearly overwhelmed and in over his head. Place was empty, he doesn’t understand English well but we still wanted to try the food.

Whatever pictures you are seeing are definitely meant for marketing purposes and not what you get. I asked for an queso and he says they don’t have. But his menu states chips and cheese $5.99 my guy is cooked.

He also tried charging my coworker for a drink that comes with his burger it literally says cheeseburger comes with fries and a drink.

Find another place this ain’t it

The food is great, the atmosphere is nice. the employees are so warm and kind.

I’m so sorry for dumping sauce, a half-eaten burrito, and tissues in your recycling bin, I thought it was an actual bin. You guys are really nice you didn’t deserve that
