its saying, it looks like the only thing being done is drinking alcohol.

the last part is just a old fashion way to say- how people wouldve talked way back when kings and queens existed.

요즘 맨날술을마시는거갔어 -> 갔 should be 같.

If I correct the sentence then it will be 요즘 맨날 술을 마시는 것 같아.

요즘 맨날 술을 마시는거 같어-> using 같어 is another way of saying 같아. (~ seem(s) like). However, we can see -같어 in many Korean classical literatures.

The sentence means (he/she) seems like drinking these everyday.
