While the majority of diners report high satisfaction with the food quality, including popular items like the smash burgers, tacos, and signature sauces, there are occasional mentions of inconsistencies regarding service speed, operating hours, and the quality of takeout meals compared to dining in.

I really like their burgers, which is why i keep coming back. But the service is terrible.
They say they are open, but when we arrived, they weren't! It also says open at 12 on the doors, but all the lights were closed.
Also, even when open, they do not answer their phones. So yeah, they are great burgers with a good price, but they need to work on the service. Also very slow service to receive your food.

Excellent. J'adore ce fast food. Les prix sont raisonnable, surtout leur menu qui tourne autour de 15-20 pour deux burgers, une frite (assez large sur le plateau) & une boisson. Les portions sont généreuses & les employés sont vraiment formidable. Je réitère mais franchement j'adore cet endroit. Excellente enseigne locale. Je recommends fortement!
