My review is solely based on the protein shakes.
I have not tried their food, though the menu looks really appealing. I tend to come here after the gym to grab a low calorie protein shake. Their shakes are really delicious and pack a lot of protein - over 40 in a 32oz. The prices are reasonable too. I really enjoy the Snappy Apple and Fresh Strawberry Banana shakes. Be sure to specify you want a protein shake and NOT a smoothie, as they have those too.
One of my favorite parts is being able to check nutritional content. The menu does not display it but it's available online.
The restaurant is always very clean and tidy. Staff is friendly and has been efficient the last few times, though I remember a time of me standing at the register for a while without anyone approaching me.
Muscle Maker Grill offers meal planning and will pack your meals for you. Great option for busy people that are trying to stay healthy. Or even someone who isn't sure how to go about making a healthy meal.
