Menu Comparison: Swig vs FiiZ Drinks
Both chains build their menus the same basic way: pick a base soda, add flavored syrups, then finish with cream, fruit, or candy. The difference is in how each menu is organized and what each chain is known for.
Swig menu highlights
Swig leans on a large menu of named signature drinks, so first-timers can just order off the board. Swig’s menu includes The Founder and the Dirty Dr Pepper, along with refreshers, Swig Energy drinks, and sugar cookies.
If you want the full rundown, see our Swig menu.
FiiZ menu highlights
FiiZ is built around customization. The menu features signature mixes, but the real draw is building your own drink from the ground up: choose your base, stack your syrups, add cream or coconut cream, and finish with fruit or candy.
If you like tweaking every detail until the drink is exactly yours, FiiZ was made for you.
Customization and diet options
Both chains let you customize sweetness, ice levels, and add-ins, and both typically offer diet soda bases and sugar-free syrups for a lighter version. Exact options vary by shop, so ask at the window if you have dietary preferences.
Price Comparison
Here is the honest answer: Swig and FiiZ sit in the same budget-friendly range.
A specialty dirty soda at either chain generally costs about what you would pay for a fast-food drink, with the final total depending on size, add-ons, and location rather than on which brand you choose.
Neither chain is consistently cheaper than the other.
