凉面 is not the same as ramen. In the USA, ramen usually means 拉面 or sometimes even 泡面. 凉面 has many types, and usually in English we say "cool _____ noodles". For example, for 芝麻酱凉面 we would say "cool sesame noodles". Hope that helps!

You can say 'cold noodles' to keep it simple. But I would say 'Xinjiang Cold Noodles Mixed With Vinegar and Chilli Oil.'

如果说是咱们这特有的，大可以直接说liangmen 拉面的翻译是ramen

cold noodles ^_^
