Sorry, there are no decent instant ramen.
Ramen is not junk. It's a bit like saying spaghetti is junk, because you only had the ready made versions.
If made right, with fresh ramen noodles and and a proper soupstock, it is an absolutely amazing dish and it's reasonably healthy too and usually plenty of vegetarian options too.
Unfortunately, it's near impossible to get it in the UK. The only specialized ramen place I know, is Ryu on Brewer Street (in London), although I do believe a new ramen place open last year (but don't know name & place).
Luckily, it's quite popular here in Vancouver, with several Japanese run ramen places. Favourite place is organic ramen, which is absolutely amazing and reasonably cheap too! (lunch for less than $10).
