In the restaurant world, a good reputation is built on time plus patience. This 52-year-old breakfast joint inspires patrons to either rabid loyalty (read: "The Dutch Baby is the size of your head!") or grumpy aversion (e.g.: "I had to wait an hour to pay $30 for a short stack and coffee"). Whatever your flavor, the fact remains that the OPH is an original worth waiting for-pre-buttered toast, fluffy omelettes ($9-$11) oozing with cheese, and housemade batter that serves as foundation for a dozen-plus unique pancakes ($7-$12).
