Ohhhhhh Deluca's.\n\nIn my experience, there is a great divide in the city of Pittsburgh, similar to Montagues vs. Capulets.  This divide is Pamela's-lovers vs. Deluca's-lovers.  I am firmly in the latter camp, and I will be pleased to challenge Pamela's patrons to a duel, as long as I have been fueled by a breakfast burrito the size of my head and innumerable rounds of coffee.\n\nDeluca's has quirks: It takes forever to get a table (because everyone's trying to eat there), the ambiance is old-school funky diner (weird mural, propensity for stickiness on the formica tabletop), and you should not expect to be pampered by the waitstaff (they do their job well, for the most part, but the restaurant is always busy, it's not a high-end place, and they aren't going to make enough in tip money off your $10 breakfast to put up with a snotty attitude from their customers).  Personally, I like this in a diner, and it is something I actively seek out.  I like to come here kind of hungover, devour a massive burrito and a huge orange juice and about three cups of coffee when the waitress has time to refill my cup.\n\nMy favorite diner is still that diner under the 16th street bridge, which I forget the name of it but it makes kick-ass biscuits and gravy.
