Last time I was home I noticed that Select had taken the former Internacionale unit and left their smaller one next door, I think these may be the ones you mention.

Bon Marche is taking on the old Select unit. Nothing to get excited about, but it does mean that this arcade has a bit of a niche of value fashion.

Bijou Brigitte has closed down in this arcade & Shoe Zone has closed and moved a few doors down into ModelZone!

So weird, this moving around business!

Its not that weird - stores often move around to upsize or downsize, to free up more appropriate space for other retailers etc.

In other news, A. Eagle has confirmed its first 3 locations for the UK - Westfield London and Stratford, and Bluewater. Its choice of Bluewater suggests it doesn't think it will be that reliant on the tourist market (which can often be very important in central London and even the Westfields). So Cardiff might be in line a couple of years down the line. It does seem like the kind of brand that could do well given Cardiff's demographic.
