This business is located inside the Capriotti's Sandwich Shop in Old Town. They have a multitude of flavors available. Each protein shake is around 250 calories and this is awesome for me, they are dairy free! I have had the dreamsicle and lemon meringue pie flavors so far and they were both very tasty and not overly sweet.
This is a very tasty and filling alternative to a bagel or doughnut in the morning. They are adding more options and will start doing a special flavor of the week and veggie (kale, beets, etc.) options in the coming days or weeks. If you haven't tried them yet, give it a shot.
I stopped in looking for the former Everything Bagels one morning and talked to the gentleman about his new offerings. I gave it a shot and was pleasantly surprised. I have been back and will continue to stop in in the future.
