Or they decided it was too small? The old Gap Kids space was (if memory serves me right - 6,500 square feet (maybe 8,000). The old Mac spot (next to the new Mac) is tiny - maybe 1500 square feet.
As for second floor of J. Crew - there's nothing. I don't know what's on the second floor now - someone once rumoured that Suit Supply had leased a bunch of that second floor space (pre their Hazelton lease). Brooks Brothers is in the basement and main floor, so not sure what the deal is.
The J. Crew is ok... I'd really like a mens store we've been totally shafted in most of their stores here.
