Parthenon is GREAT if you know what to order. It's been my go-to brunch place on IDS since I've lived here for 20 years! One customer posted that the manager was not too warm with customers and that's true! Some of the staff though (there's one gentleman in particular who's been there forever) is super-pleasant and very accommodating. The brunches (especially the omelettes) are delicious and the portions very generous. For lunch, I HIGHLY recommend the veggie sub. It's HUGE and comes with a ton of fries and it's really yummy. It's a very share-able dish as well. Their lox platter comes with a (real) bagel (none of those Tim Horton's wannabe cakey things), cream cheese and butter on the side and a salad with your choice of dressing. Great stick-to-your-ribs fare any time of day!
