I honestly don't understand the fuss about the Original Pancake House. It's ok, but there are a variety of Twin Cities breakfast places that are their equal and many of these are less expensive.
What do they do right? Their service is generally exceptional. Coffee is good as well, if you like the stronger stuff. There are some "foofoo" items that my wife, mother and sisters like, such as the stuffed crepe and flavored pancakes.
What's average or worse? Waiting time can be extreme. Call ahead for a time to come when a table will be waiting for you. It's crowded. In many areas the tables are very close to each other. This leads to a lot of noise at times, too. The menu is limited for mainstream food choices. Many breakfast places offer far more combination type meals. The Original isn't cheap. A small side of hash browns was something like $4.50. Unfortunately, almost every time I come here I find myself needing to order one or two sides because they're not offered as part of the meal. At times, this INCREASES the cost of my breakfast by nearly $10! It's a chain - don't we have enough chain restaurants already?
The Original is has a lot of unique products, but is expensive and their portion size is small. Maybe this is why my wife and mother like it (the food is different from our usual breakfast places), yet I can still walk away still hungry after spending at least five dollars more than most chain and local breakfast-oriented restaurants. I once was completely full after eating at the old Wayzata location, but it cost just over $20 with tip for my food. I find that unacceptable. At least they finally put hash browns on the menu (at least at the Maple Grove location). For years, you couldn't even get that.
