First start at the slash and work your way left: "com -> noodles -> tasty -> mobile" - then jump back to the slash and work your way right: "italian -> fettuccine".
This is counterintuitive and I doubt most users understand it. "com.noodles.tasty.mobile/italian/fettuccine" makes more sense to me.
Also, I think TLDs like "com" and "edu" and now "io" and "cool", etc, are misguided. I wish we had "country.language" as the only TLDs. For instance, "us.en.apple.www/mac". I see several advantages.
One, if "us.en.apple" and "uk.en.apple" were different entities, it would make legal sense, whereas "apple.com" and "apple.cool" being different entities makes no sense. Two, a use would likely notice if they ventured outside their usual TLD(s), and be less surprised by the different entity. Three, these TLDs could have rules about allowed characters; eg, only ASCII in "us.en". This would make homoglpyh attacks much more difficult.

Also I would have put the domain name in the reverse order - in order of size so, for example, the BCS address would read: http:/uk.org.bcs/members. The last two terms of this example could both be servers if necessary."
