This place is very good, but I think it has been overly hyped and have some doubts about whether it's really as good as its supposed to be, at least based on a single visit.
Decor is funk chic. I am sure the kitchen is very clean but the dining room does not appear to be so. I had a special of banana pancakes with walnuts, which were delicious. The egg dishes of other members of our party were good too. Though only open for 90 minutes at the time of our arrival, they told us they were already 86 on the waffles.
We arrived fairly early and a very short wait in line, though the kitchen was quite slow in producing the food. When we left, the line was way down the block.
My personal feeling about this place is that it is a pleasant place to go if there is no line, but I would not wait for two hours to be seated - it is not quite that heavenly. Given the small number of table and slow pace of the kitchen, any waiting line does not move very fast either.
Service was quite friendly and pleasant.
