As many others have noted, it's not as if this place invented "the sandwich" but read my star rating: I'm a fan. The food is good, I haven't had a sandwich that I disliked. But it's the service that I was impressed by. Art, the owner, seems to really take interest in each customer that crosses his path. It's a breath of fresh air and something you might not see at the chain next door.
I enjoyed my Roasted Turkey sandwich. I'm picky about cold cuts (I've basically signed an exclusive with Boars Head) and these made the grade. The bread tastes freshly baked too. The mozzarella sandwich is tasty too. Thumbs up on the turkey chili as well, can't beat it on a chilly day. If you get a drink be prepared, they're basically in vat size cups. They offer your typical 1/2 sandwich & soup lunch specials as well.
To touch again on the great service, on my last visit Art literally sat down with me and chatted it up. It was the end of the lunch hour and the place was pretty much empty. He asked about my job, how I like downtown etc etc. So friendly! Hell, I might even just come back for the conversation! You should stop in and say hi. One of the few lunch places downtown where you don't have to have a fanny pack to fit in, this cafe is worth a try.
