I've been away a while, so this may have been covered, but in my never-ending search for a decent hoagie I've finally found one in Studio City: it's Studio Subs.
Their standard Italian comes without lettuce, but you can ask for it. Otherwise, it's almost perfect. Not as flawless as White House Subs in Atlantic City, NJ, but a damn good effort.
And don't look now, but I've also been happy with Jersey Mike's--a chain, yes, and on the light side, but it hits the target.
