First things first, this is a cash only joint, but they do have an ATM if you need.
Original Breakfast House makes me wish I'd never awarded 5 stars to any other establishment before because it is truly a cut above. It's the whole experience from the old school ambience of the space to the kindness of the staff to the omg amazing food. It's a really special place. There's nothing contrived about it.
How could I have missed it for 20 years?!
Try it. You won't be disappointed, and you will likely be back again and again.
