    This place is such a welcome addition to Lake Ronkonkoma! Honestly, so glad to finally have a solid halal Mexican spot in the area—the options were way overdue. The food is super fresh, full of flavor, and they don't skimp on portions. The staff here are awesome, too. Really friendly, fast with your order, and great customer service all around. If you're in the mood for killer halal burritos or tacos, this place completely nails it. Highly recommend checking them out!

    DISGUSTING!!!! Came here for a quesadilla & 2 crispy tacos first they messed up my order gave me soft soggy tortillas that broke the minute I picked my taco up! The steak pieces are so rough and hard to chew the quesdilla was disgusting! I payed 30 dollars for this by the way and the tacos were ordered as a kids meals that came with nothing! I will be calling who ever I can in the morning through the town to get this place shut down! I seen the bad reviews before i came but I thought let me give them Grace HELL NOOO SAVE YOUR MONEY YA’ll CHIPOTLE CHEAPER AND BETTER AND YOU GET THE SAME STUFF FOR ONLY 15 dollars
