Went here on a very cold Saturday afternoon with my fiance and her aunt. I've been here several times during the lunch/brunch hour on the weekend and very single time it's a decent half hour wait to get a seat. Make sure you put your name in when you get there and for you to be seated your whole party has to be present.
Pamela'ls is an excellent place for breakfast! It's styled like a 1960's diner with old pictures all around the walls and some very unique colors to the restaurant. This place has by far the best hotcakes I have ever had! I'd highly recommend the strawberry or chocolate chip and banana hotcakes. They are really thin but will fill you up. All 3 of us ordered hotcakes for our meals and were very pleased with both the quality of the food and the service by the staff at such a busy time.
Pamela's is a beautiful Pittsburgh staple. A unique atmosphere, excellent food, great staff make this place easy to return to time and time again.
