I'm on an ambitious gastronomic quest and would love a little guidance from some locals. You can help me by answering the following:
If you could only have five more sandwiches in the London area for the rest of your life, what would they be?
Please try to limit them to sandwiches that we could all purchase (i.e. not something that your grandmother makes once a year). Otherwise, you can be fairly liberal in what you decide to count as a sandwich - burger, taco... perhaps even a pork bun if you really feel strongly about it.
Feel free to give a bit of justification for your choices where appropriate.
Thanks in advance!
