Now, it looks like Darren did an excellent job of summarizing the amazing quality of the meat, fries, and wellm even the history of the name. Kudos Darren.
The only thing that I can add is about their salads. It might seem a little ridiculous to be looking for a salad in the southside, but Lesvos has a great greek salad. All the components from lettuce, tomatoes, and greek olives, are all fresh and very crunchy. The lettuce also has a tangy Vinaigrette lightly drizzled on it. All these ingredients paired with the amazing meat selection of Lesvos makes for a delicious and filling salad. Also their tzatziki sauce is actually made with fresh yogurt as opposed mayonnaise that many other places use. So its healthy.
