    I came in for the first time to this location due to it being convenient. My drink was not my favorite but that is just a preference so it is nobody's fault, my low rating is due to the poor attitude from management. The manager, who's name I believe to be Mercedes, seemed nice but seeing the way she talks to her employees is not okay. She is very rude and negative and I will not support an establishment that does not treat their employees with kindness and respect. I stood there and watched her belittle and disrespect one of her employees while simply waiting for my drink. I will not be returning and hope that such an attitude is corrected.

    Great experience - ordered mobile pickup and order was made within 10 minutes even through they were really busy on a Sat morning. Interior is clean and good amount of seating available. Food was good too and order was correctly made. Has a restroom. Thanks

    I had a DR appointment near that area, so I decided to give this location a try. I met my daughter here, and when we ordered they messed up her drink. Then while drinking mine, I realized it didn't taste right. I ordered a bagel sandwich, and got food poisoning!! I've been miserabley sick, and in the hospital since Tuesday. ABSOLUTELY DO NOT GO HERE!!!

    Normally a go to. I would always have great service, but recently had a bad experience with a rude employee taking my order. Didn't catch her name, but she was not one I've seen before. Not sure what's with the attitude. Managers need to talk with their employees on how to talk to a customer or at least that one employee.

    Terrible atmosphere employees were extremely rude and I overheard them gossiping.. they didn’t even try to hide it. They make customers feel very uncomfortable!!! I do not recommend this location to anyone
