Obviously the best thing about a convenience store is the convenience of it all. I like looking into my fridge, saying "oh, I need milk" and being able to walk a block away and get my milk. It's close to several apartment/condo complexes so I'm sure I am not alone in my sentiments. Is there a premium? Yes, there's a bit of a "convenience store" mark-up.
They sell Otis Spunkmeyer cookies (so try to find out when they're fresh), which I always enjoy. They also sell Boar's head deli sandwiches, Egyptian tea and an outdoor patio, none of which I have yet taken advantage of. At one point they advertised hookah but I don't think they do anymore. Hodge podge? A little bit. Well done? I couldn't quite tell you yet. They currently have a facebook page but not an independent website.
