ANSWER: As several readers correctly guessed, this is the Black Forest ham "Guest Sandwich" at Ula Cafe. In addition to the ham, it has Swiss cheese, housemade dill pickles and honey Dijon mayo. It's grilled, and usually on rye.
Welcome to Week Three of a new JP Patch feature, one that I hope you'll find entertaining.
Each Saturday I'll post a photo from a dish I've eaten at a JP restaurant. In the comment section, make your guess about which restaurant served the meal. I'll circle back with the answer on Monday.
Take a look at this week's meal and Guess the Restaurant in the comments. Good luck!
(I'll give an extra hint this week: This sandwich came with different bread than was on the menu — it was late in the day and they were out of rye.)
