The partnership who gave us Rye on Market opened a new restaurant at 605 W. Main dubbed Atlantic No. 5, in late October. If you weren’t aware of it, count yourself among the many who haven’t been there yet. Lots of room at the counter thus far, but that won’t last long.

Named after a de rigueur lunch pail of the working class in the early to mid-20th Century, Atlantic No. 5 keeps the menu simple, serving a variety of breakfast and lunch sandwiches, a few substantial plates, salads, soups and drinks throughout the day before shutting down in the early evening—for now anyway. It will also serve as a music venue, so you can bet its hours will be extended if that portion of the biz takes off.

If you’re in need of a primo java fix, it has that, too, and if you just want something from the deli case to eat later, that’s also an option.

The century-old space has been stripped down to its primary brick and wood surfaces and adorned only minimally beyond that. It’s clean and that modern minimalist way that gives a glimpse into the past without feeling old-country-store dated.

And as you might expect with its name, some of the décor centers on cool lunchboxes. Go see if you didn’t have one or more of the throwback carriers when you went to school.

It’s open Monday through Friday from 10 a.m. to 6 p.m. and Saturday from 10 a.m. to 2 p.m. No Sunday hours.
