I can get lost in here for hours, even though it's not that big. There is clearly a lot of care taken by the proprietor in choosing the most aesthetically pleasing and functional materials for all your writing needs. There is also a small section of art books in the upstairs space.
Staff is friendly and helpful, big plus!
It's definitely on the pricey side (I wouldn't necessarily come here for basics) but you definitely get what you pay for.
