Burger 21 Kennesaw Marketplace — Restaurant in Kennesaw

Ok. So here is why I found a reason to write a review. I was truly excited to try this place out because I am new to the area, and they have a "vegan" veggie burger. Walking in, it was very clean. (Five stars for that). The staff all appeared fairly young, and SOME were polite. Walking up the register, the girls were chatting away and gave me a look as if to say "what was I doing there", when I attempted to place my order. Overall, neither of them was very friendly and they seemed uninterested to be there. (You can always fake it ladies). I was told to sit at the bar to wait for my order, which took over a couple of minutes. I understand it is made “fresh-to-order”, but the quality of the food did match the quantity of time it took to bring it out. My burger looked as if it were thrown together. Ingredients were scarce; all of the lettuce laid in the bottom of the plastic container, and I received one strip of a roasted pepper. It was also not very flavorful and only slightly warm. The fries were cold. Once again, I was seated at the bar for quite a minute and truly expected hot food. What also confused me was the amount of individuals in the kitchen. There was a good number of employees back there and it still took an extended amount of time for the food to come out. In the front, there were employees on their cell phones and some were just standing there in small groups socializing. I have worked behind the scenes of food services, and most of the activities these employees were doing would not be condoned. Overall, the man who I believed to be the manager, really needs to be somewhat stricter with his employees. The place may have looked spotless, but the service and...

This was my first time visiting Burger 21 and I will probably not be back. There was only one customer in the seating area waiting for food and one customer behind us in line to order. We were not greeted when we came in and had to wait for someone to come take our order. The cashier was rude and seemed as though he didn't care to take our order. A door dash driver walks in, goes around the other side and interrupted the cashier, cut in front on everyone waiting to order, asking where his orders are. The cashier stopped our order and interacted with the door dash driver. After we placed our order, got our drinks and sat down, I realized my cup was leaking. The cashier was no where to be found to ask for another cup. He came out when other customers came in to order and quickly disappeared once again. When I was able to get a second cup, it too, was leaking. Our food finally came out and the server quickly sat it on the table and walked away. Not realizing that you have to ask for condiments, since no one ask us if we needed any, we now had to wait until the server came out with someone else's food to ask for ketchup. We were given 2 small containers with maybe a table spoon of Ketchup per container. At this time we realize that my daughter's cup is also leaking from the bottom. Now to the food. The bread is dry as if it were from the day old bread section at the market. The burgers were overly salted, and the fries were dry and over cooked. The prices are way to expensive for the food we received. $40.10 for 2 burgers, 2 orders of fries, and 2 small drink. We had been wanting to try Burger 21 out for a while and given the time decided to go that day much to our...

I would like to publicly recognize the outstanding work Manuel does at the grill station. From the moment you see him in action, it’s clear he knows his craft to perfection. He has impeccable control over cooking times, temperature management, and getting the exact doneness for every cut of meat—whether it’s medium rare, medium well, or well done—always ensuring it matches exactly what the customer ordered.

Manuel keeps his workstation spotless and well-organized, which is essential in such a demanding area as the grill. The way he handles utensils, meat, and other ingredients reflects a high level of hygiene and professionalism. He works quickly and efficiently, even during peak hours, without ever compromising quality or presentation.

He’s also a great team player—constantly communicating with the kitchen and servers to make sure orders are delivered on time and in perfect condition. His respectful and friendly attitude helps create a positive and motivating work environment.

When it comes to customer service, it’s clear that for Manuel, it’s not just about cooking—it’s about providing an experience. Whenever possible, he checks that the food meets expectations and that the customer leaves satisfied. This shows his commitment to excellence and his passion for what he does.

In short, Manuel is not only an exceptional grill cook but also a professional who takes care of every detail—from selecting and preparing ingredients to the final presentation of each plate. His dedication, skill, and positive attitude make him an invaluable member of the team and someone truly worthy of recognition.

Definitely an example to follow...
