- DCDave Castel3 days ago3.0Food is usually good depending on who’s working. The staff tonight were disappointing at best. Ordered at 7:10, pickup 7:28, food done at 8:05. It’s one thing for you to take time with your food it’s another to give greasy mushy food. Also, in food service, wear shoes… candles in the kitchen? Thats wild. Will return but not for a little while. Maybe a change if ownership.
- BBBurk3 days ago1.0I got the birria tacos and a steak quesadilla. Birria was alr, the steak quesadilla pmo, the total was 36 bucks. They wanted to mix chix in bc they only had a little bit of steak atm, I said no and they still added it. I do not eat chix that’s why I said no, like broo. I asked them if they mixed chix in my quesadilla when I got it just to confirm and they said no. I get home go to take a bite and there 90% chix in it, they played in my face.
- CHChristina Hernandez4 days ago5.0We visited saturday night 1am. Great service by Adam and amazing HOT MADE TO ORDER FOOD. We ordered wings , french fries , steak quesadilla. All fresh and delicious flavor. Chipotle sauce was great. We will definitely come back.
- DLdiana lember5 days ago5.0I’ve been to Guac Island Mexican Grill twice now, and both experiences have been great! The first time, I tried the birria tacos, and today I went for a Mexican bowl. Everything has been fresh and delicious, the service is excellent, and the prices are really good!
- AWAndrew WattsOct 3, 20261.0Okay so pretty much i walk in to see 1 person working all by himself didn’t think much so I ordered 3 tacos. I ended up waiting 45 mins just for the food to taste terrible please don’t come here it’s not worth it. I never write reviews but I couldn’t help myself this time this place is horrendous.
