I was at LHR T5 Galleries South this past week, which is the first time that I have been there since the changeover. Since make OW Emerald (AA ExPl), I have been frequenting the Flounge instead. On my last trip, I travelled with two other companions who were eligible only for Galleries, so I thought I'd go along.
The food is significantly downgraded, IMHO. Baked beans and a potato as a main option? Might also be my faulty memory, but the wine glasses seem to have shrunk as well. Now that there's no ice cream, there's another blow.
