Hamleys have done alot of research in to this store, believe me. The traffic at T2 is ideal for this type of venture, as it would be if Harrods were in exisence now at MAN, based at T2 rather than T1.
This store is just the forst of several elite outlets to open at all three terminals over the next year as they are redeveloped.
Both T1 and T3 will undergo major retail development starting this winter.
