All of them. Avoid town as much as possible as it's too much like hard work with two LOs!
If I do have time I never go in Next, Warehouse, Oasis, Jane Norman (noticed yesterday on the way to swimming it's shut now), Topshop, Select, Quiz, French Connecton, Phase Eight, BHS, Debenhams, TK Maxx, Monsoon.
A lot of our shops have shut down in recent years (Mango, I still miss you) but from what is left I like to have a gander in Zara, M&S, Accessorize, H&M, Gap, New Look, Laura Ashley. That's all I can think of, pretty poor really for a large town centre.
