    Never any employees

    The drinks and food are always amazing, and I've never had an issue with the quality or the employees themselves. My only concern is that the staff is often in the back, which I completely understand since they're probably working. However, there are times I've waited up to five minutes or longer just for someone to come out to the front. Maybe adding a doorbell or some type of alert would help let employees know when customers are waiting. 3 starts because the wait.

    The smoothie selection is strong: Items like the mango-a-go-go,strawberries wild and the açaí bowls get frequent mentions as hit choices. For those wanting a quick healthy (or at least healthier) treat, this Jamba location gives a convenient option in Fontana--a smoothie or bowl works well for on-the-go. Açaí bowls and oats toppings (strawberries, granola) are available and appeal to those looking for something more substantial. This Jamba Juice location in Fontana is a good casual stop when you want a smoothie or bowl and are okay with a bit of variability in service and execution. It hits the basic desire for a refreshing snack/meal alternative to burgers or fast food. Erika was one of the employees and she was super cool and friendly. Made the experience even better.

    Perfect treat on a scorching hot day! Cashier helped us adjust our menu selections to Small sizes (small not listed for some items) which we appreciated because I didn't want my kid drinking a Medium all on his own just because he was choosing a special seasonal flavor. (2/5) Kids' blueberry strawberry blast - tasted a tad sour and healthiest out of the 4 smoothies we had. I would only get this for health reasons for kids and not for taste if I had to... (5/5) White gummy bear (from their secret menu) - was so good! Probably the least healthiest considering it contains three different scoops of sherbet but I loved it! (4/5) Orange dream machine - classic orange creamsicle flavor (4/5) Seasonal classic watermelon - nice natural flavor!

    i'm a little annoyed, the discount was not applied. yet nothing has changed. didn't want to give the lady at the register a hard time but it was upsetting i came here on black friday and they bowls were each $4 off i come back today and apparently they are buy one get one $4 off but where does it say that???

    Impossible Handwich

    Under staffed. Came to this location during lunch time and there was only one person working. Asked for an impossible handwork and it was given to me really sloppy. (Photo included). There was only one other customer when I arrived. Arrived 12:15 order was ready by 12:40. Employee didn't greet us until customers who arrived after us were addressed. We only had two drinks, a parfait, and the handwich. Overall I would not return to this location. Customer service sucked and it took forever to get out of there.

    The drinks looked as if they sat for hours even though they were just made 15 minutes prior.

    Disappointed. I usually love coming to this location because I hate making my own smoothies and the Jamba on Sierra never tastes too fresh. I guess I better dust off my own blender though. Today's visit was a quick lunchbreak run for me and a few others. I was in and out in about 5 minutes, a bit of a rush so I didn't check my drinks before leaving. I should've. They were poorly mixed and mostly juice. Little to no sherbet and they kept leaking because there was no slush to the "smoothies". To add to it, there were powder clumps in two of the smoothies. No one finished their drinks and I feel like it was a waste of money and time.

    i poured the Gotcha Matcha with Sweet Cloud Whip into a cup and realized it was 90% cold foam.

    The workers were kind and quick however my matcha was really messed up, hopefully they learn how to make it better next time. I ordered light sweetness but it was overwhelmingly sweet and could hardly taste the matcha flavor. So upset because this drink was $6 for a small :(

    This has to be the worst Jamba in CA. Every time I come they're out of something and it always smells like the new guy is burning the bread.

    Very disorganized staff. Took 30+ minutes to receive our order. Two stars because the drinks are decent.
