You can always count on All About Books & Comics to have what you're looking for. The store has a great browsing feel to it. The staff are there if you need them, but not pushy. It makes for a great comic shopping experience.
All About has a great layout for their titles, as well. I see a few too many places that place titles behind others on their racks due to a lack of space. All About places them all out there, face out, so you don't miss anything hiding. I also like that they sell a lot of old back issues at cover price.
The only thing that would make All About Books & Comics even better, is if they had a few couches and chairs for comic collectors to hang out, read and chew the fat.
