"via Abercrombie" on Abercrombie lane (an alley) probably has made the best sandwiches that I've had in Sydney so far. The only warning is that they're dangerously large. Even for a big eater they're generally 2 meals worth.
Otherwise I've had a hard time finding good sandwich spots in the CBD. about 7 years ago
The big bite on Pitt similar to Abercrombie it is in a small ally and they are also HUGE! about 7 years ago
