ーI've been eating and eating this bowl of Ramen, but it still looks like it's full.
「ラーメンをずっと食べているのにまだ山盛りのようだ」＝「このラーメン食べても食べても全然減らない」
I've been eating and eating ... で「…をずっと食べている」
it still looks like it's full で「まだ満杯・山盛りのよう」
ーI've been eating and eating this bowl of Ramen, but it doesn't seem like it's disappearing at all.
