Soda Bar Frequently Asked Questions
How does it work?
It's easy and self serve (but we can help if you need it). You simply pick your syrup flavor or flavors, add ice, add in the carbonated water from the tap, mix and voila, you are done!
Do you sell the syrups?
We sell select syrups in the store. We currently do not sell the syrups online.
What if I have dietary restrictions?
The sodas are caffeine-free, gluten-free, vegan and dairy-free. We do have the option to add in unsweetened coconut milk.
What sizes are available?
We have a 12 oz cup for $2.50 and a 20 oz cup for $5.00.
What is cool about the cups?
Traditional paper cups hide a layer of plastic inside. Nothing Cups don’t. They use a water-based coating that’s food-safe and vanishes in under 180 days. With built-in lids, they create less waste, streamline operations, and save space.
In addition, unlike regular paper straws, Nothing Straws stay strong for hours without getting soggy. They’re thicker, sturdier, and built for every kind of drink.
