Hmm. IMHO the LHR T5 Galleries both First and Club are unfortunately very poor product and are worse in basically all categories in compare with for example Flagship lounge (not even mentioning the Flagship First dining). It is a shame because the BA galleries are (basically) the only lounges in T5 so there is no competition for them. In T3 it is the same product in Galleries, but there are much much better alternatives such as amazing Qantas or Cathay lounges (if we stick to the OW).
