"Often imitated, but never duplicated. South Union is the original ciabatta bread sandwich shop. I have been coming here for years and you can always count on the quality of the sandwich. I usually visit here about once or twice a month, but for about a year my office was just a couple of blocks away, so I was visiting once or twice a week. I slowly made my way through most of the menu, but hands down my favorite is still Sarah's revenge. This place gets busy quick, so you want to go before noon if you can. Even though dining area is spacious it fills up quickly."
