We are visiting in early September and would like to know of good breakfast/brunch restaurants in the area?
If your budget permits, maybe Nemacolin? Be aware that parking is a real problem near the main falls in Ohiopyle now, thanks to the visitor center construction.
The Ohiopyle Bakery and sandwich shop overlooks the falls and has coffee, baked goods and breakfast sandwiches. It is also a great place to get a box lunch for whatever adventures you have planned for the day. A short trip to Confluence will get you a classic diner breakfast at Sisters Cafe.
Not much real close for breakfast but I second the Ohiopyle Bakery. Breakfast sanwiches, muffins, bagels...
If you want to travle back to the Donegal area, about two miles from the Turnpike interchange on Route 31 west is Brady's Restaurant. Very good family home cooking restaurant.
