Sure, this place isn't as cheap as you want it to be. Maybe the food isn't the most amazing. But it's a diner. It really wins at being a diner.
The coffee is bottomless. Like they're not kidding. Even after I'd loitered over a book and my food had long been cleared away, they still kept refilling my cup until I had to beg them to stop. Because I have no self control with coffee and will just keep drinking it until my heart explodes. Luckily, diner coffee is weak enough that it'd really take a lot.
I got a crepe omelette, which was strangely delightful. I ate until I was stuffed and my plate was still 2/3 full. So bring an appetite (and then some).
The decor is what really makes it. The weird cat/butterfly/bird stained glass is something special.
