Pamela's is an institution in Pittsburgh. I tend to be more of a savory eater than a sweets guy, but this place does really well on both. On the savory side, Pamela's makes very competent omelets and gives plenty of options on egg whites only/eggbeaters. The most famous aspect of their savory foods is the "hash browns" which have some spices/herbs that almost taste like a super mild and buttery Indian Masala. They are really really great--ask for them to make them extra crispy. On the sweet side, their crepe-esque pancakes are delicious. As mentioned, I am not much of a sweets guy, but after my omelet, I do enjoy sneaking a bite or two off of the edge of my wife or child's buttery, mapley pancakes.
In Shadyside, don't be surprised to see Lynn Swann, and expect to wait for a table on a Saturday or Sunday.
