May be a cultural aspect. A British pub grub staple is &quot;Fish and Chips.&quot; In the kind of food-oriented gastropub the parent comment is alluding to, you&#x27;d see an explicit reference to the species, possibly even its provenance. E..g &quot;Halibut &amp; Chips&quot;, or &quot;Line-caught Atlantic pollack served with hand-cut goose-fat Jersey Royal chips&quot;. It&#x27;s really a 180 from no-nonsense pub menus, which are in themselves a recent innovation. (First pub I went to regularly your choice was a packet of crisps or a pickled onion from a dirty glass jar on the bar.)
