I've been there twice. once very randomly, and I didn't even live in the area then, but the second time I needed to print some business cards very fast and this was the closest place to me. And for some weird reason I've been doing that(printing business cards) a lot for the past few months so trust me I'm an expert now. The owner, who is an Egyptian guy, takes care of you really well. He's friendly, interesting and fast. The prices are pretty reasonable, he shows you different papers he can print them on and lets you decide which ones the best. He helps you in fixing the file without charging you extra. ( I actually had "oh I just added a . to your line that goes another $20" before)
oooooh and he has the most interesting art works on his wall. there are some VERY interesting paintings(wish I could remember the artist's name) which takes several minutes to figure out what they're about. So there's no way you get bored in this little shop while waiting for your prints to come out!
