The verdict
This is the one. The Lomito Beef Sandwich at Buenos Aires Cafe earned the first perfect 10.0 in StackSandos history — and with it, the title of best sandwich in Austin.
A perfect score isn't handed out lightly. The Stack Score mirrors pairwise ratings on Beli, where a sandwich can only dethrone the champion by consistently ranking above it. The Lomito cleared that bar — and then some.
It dethroned the Gourmet Italian from Tucci's Southside Subs, which held #1 at 9.6. That's the system working exactly as designed: a new champion only takes the crown when it earns it, head to head.
