Marilyn Monroeville Mall was popular with the Kennedys and Joe DiMaggio. That's about all I know about it.
Except that I've been here 3 or 4 times now, and the most recent time spent about 4 freaking hours here because the people I was with - to put it mildly - are shopaholics.
There's a lot of good stuff in this Mall, and some really cool stores like Inkas Crafts and Pearl Of The Orient. The Hot Topic is good, and the food court has a decent Sbarros and a lovely coffee shop named Gloria Jeans. Unfortunately, the bubble tea stand that I enjoyed awhile back seems to have been closed down, at least it was the last time I was here.
Overall it's a great Mall, it's walkable, it's accessible from the main roads, and it's got a cool outside-shopping-street part of it attached which makes it a hybrid of the new kinds and old kinds of Malls, although honestly Pitt is way too cold for that kind of thing really. It loses 1 star for so many of the stores being overpriced, and another for the Bubble Tea being closed down.
