7 Brew vs Sonic
Cup sizes, price per ounce, menu range and rewards — 7 Brew against Sonic Drive-In. The per-ounce gap is 32% in Sonic’s favour.
A 7 Brew Medium is 24 oz at about $5.51 ($0.229/oz); Sonic's 20 oz medium cherry limeade / slush is about $3.49 ($0.175/oz). Sonic is about 32% cheaper per ounce, though 7 Brew's cups are larger. A different category. Sonic is the value soda-and-slush option and it is unbeatable on price; 7 Brew is the coffee-and-customisation option. They only really compete for the afternoon cold-drink run.

What each does better
Sonic strengths
- Cheapest per drink of anything compared here
- The Route 44 (44 oz) is the biggest single cup on this list
- Half-price drinks during happy hour is a genuinely strong offer
Where Sonic falls short
- Not a coffee chain — the espresso range is very limited
- Soda and slush focused, so the flavour library is shallow compared to 7 Brew’s syrup wall
- No equivalent to 7 Brew’s customisation or secret menu
7 Brew strengths
- 16 / 24 / 32 oz ladder — bigger at every tier than Sonic
- 217 tracked drinks with a large syrup and milk library
- Every drink can be rebuilt: sweetness, milk, syrup, temperature
- A large documented secret menu the stands will actually build
- 846 stands across 38 states, all drive-thru
Where 7 Brew falls short
- No indoor seating — it is a window, not a café
- Prices and availability vary by stand more than at a corporate chain
- Nutrition is not published per drink, so figures here are estimates
- Concentrated in the South and Midwest — thin on the coasts
