The trade-offs

What each does better

Sonic strengths

  • Cheapest per drink of anything compared here

  • Half-price drinks during happy hour is a genuinely strong offer

Where Sonic falls short

  • 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

  • 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
