★★★★★ 5.0 Traveling Life · Dec 2025

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

★★★★★ 5.0 Asad Aman · Dec 2025

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!
