When Roula Karahalios came to the United States from the Greek island of Crete, she brought with her a rolodex of recipes that she now uses in the kitchen at Roula’s Cafe. Roula and her son Nectarios skewer chicken souvlaki and slice lamb for gyros. An array of meats, cheeses, and veggies as well as marble rye bread and croissants come together in custom deli sandwiches. Patrons also get to choose what fillings go into omelets and breakfast sandwiches, but not whether John Goodman plays them in a made-for-TV movie. Inside the café, a painted owl overlooks blue-topped tables from the branch of an oversized tree mural on one wall, and black-and-white checkered flooring gives the eatery the vibe of an old-timey diner.
