The extensive menu offers something for every craving, from outstanding Cuban sandwiches and delicious pancakes to crispy homemade hash and thick maple bacon, all served in a charming diner setting with a fun ambiance and classic soundtrack. The friendly, attentive staff make every visit enjoyable, whether it's breakfast, brunch, lunch, or dinner, and the generous portions combined with reasonable prices keep me coming back time and again.
