Zupa's is a great little diner for the entertainment district office lunch crowd. It's got all the basic trappings of your standard Greek / Casual Diner. Great burgers, souvlaki, deli sandwiches, fries, gravy, etc.
They also serve breakfasts and will generally put together anything you want without much fuss. I usually get 2 eggs with bacon on a bagel with tomato, lettuce and mayo for $5 or so.
Usually 1-2 lunch specials each day of the week. I wish I could remember what they all are, but there's usually Shepards Pie, Pot Pies, Chicken Legs, Spaghetti & Meat Balls, Fish & Chips, Philly Steak Sandwiches and my absolute personal favourite, Deluxe Roast Pork Thursdays. It's virtually a religious tradition at my office.
The other really good must-have is the Egg's Benedict. Best I've ever had. I often head down there on the weekends even if I'm not working just to get it.
Leo (the owner) is great and is always smiling & friendly. Service is usuallly quick unless you get caught during the middle of the lunch rush, but even then, there's usually 2-3 cooks taking orders and making food.
Lots of space to sit down inside, but it's not much to look at, unless you're big on soccer (or some other sport) which is usually playing on the TV. Great place to get a good, home cooked meal and kill a little time.
