Saint Mark's has a good selection, but it's not worth the obnoxious staff. People are hired to work there because they fit the punk image of Saint Mark's Place, not because they know anything about comics, and they overprice their stuff.
This place has a good selection, especially if you're looking for adult books, but the staff acts as though they are bothered by you if you try to ask them anything.
While they have the most varied selection in Manhattan, this place isn't as great as it's made out to be. Most of the staff is hired for their looks, not their knowledge of comics, and they do not offer good prices or deals.
Roger's isn't worth going if you're looking for anything new, but it's a great place for older or vintage books. If you're looking for something very hard to find, he usually either has it or can find a way to get it, and he'll offer you great deals and prices.
Midtown is the best place to go for comics in Manhattan, and they have a great location. Their friendly staff will help you find anything you need in their wide selection, and they offer good prices and discounts as well.
There's nothing really special about the products at this place, its small and doesn't really carry anything out of the ordinary, but the husband and wife team that own and run the store are the nicest people. The prices are sometimes a little steep and the products a little dusty, but their friendliness more than makes up for any of that.
This is a terrible place to shop, the service is terrible--they are very rude, and often just decide to close the store up to a half an hour before they are supposed to--and their food is often expired or rotting. I once saw a man standing in the fruit aisle eating the grapes out of the bags.
Located high up in a building with an obscure entrance, Nippon leaves no outside clues as to where it is located. But once you find it, you'll find that they are very friendly and willing to work with you to fix your problem.
Great atmosphere, a cozy little place to hang out. The food is really great, but the prices are a little high ($5 for a hot chocolate, but it's probably the best hot chocolate ever).
I have to agree with all the other reviewers, good and bad...and I definitely recommend it for shopping or just a fun afternoon. However, I don't recommend this place to sell your old books unless you have a LOT of them, or they are very rare, or otherwise valuable.
