Pros:
Very good food (I got the waffle breakfast with eggs and sausage and it was delicious)
Good service even in the middle of the night (we had a friendly and attentive waitress)
Charming retro decor
Con:
This place is filthy. Our booth was covered in crumbs, shredded lettuce, other people's hair, and even dirty silverware between the cushions. It was gross. We only stayed to eat because there was nowhere else to go and we were hungry, but it was disgusting. The waitstaff does not seem so busy that they couldn't take a minute between customers to clean the booths and make sure that the next guests won't have to sit in filth.
It was my first time coming here, and although I liked the food, I can't imagine willingly going back and sitting in those dirty surroundings again.
