- DVDiego ValdiviaDec 25, 20255.0Pretty good smoothie.
- JCJoyce CarotaDec 1, 20251.0Very poor customer service early this afternoon. Staff opened door from break and promptly disappeared from view after pointing to a screen for me to make an order. I couldn't find my usual drink on the screen, looked for her, called out hello, no response. Waited a bit, nobody appeared, so we left.
- JFJward the FoodieNov 11, 20255.0The 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.
