It's not difficult to find. The exterior looks nice enough with a classic blue awning. The spacious layout provided plenty of seating. Though not elaborate, the interior was comfortable and pleasant.

Just what you would expect from a classic diner type restaurant. I got the hot beef (they call it Manhattan) it was overly salty gravy, tender beef, mashed potatoes and basic white bread. Total comfort food! The side salad was crisp and fresh. We also got the tres leche cake (3 milk) and it was melt in your mouth delscious.

Come here quite often with my family when they are in town to visit. Always great service and great food. I highly recommend the Gyro, Double Cheese Burger, and the Crispy Chicken Sandwich. If you are like me and want to experience a meal how it was before life got too complicated, this is the place for you!!
