A sage poet (Warren Zevon) once said, when asked about his life's mantra: "Enjoy every sandwich."
Here's an underrated/unexpected suggestion: Corner Cafe. Diversity and quality. They have a broad sandwich menu for lunch, and they execute everything with aplomb. Their Italian sausage sandwich has long been my go-to, but I recently tried their blackened chicken sandwich and I was blown away. I've grown weary of lightly-seasoned proteins with a couple of sear marks being passed off as "blackened," but this one truly fits the bill. Highly seasoned and completely blackened, accented with a self-applied jalapeno jelly...man, that thing works. Lots of other options as well. Don't sleep on this place, and if you are under 60 (70?) it will make you feel young because you'll be the youngest person in the joint.
