First and foremost, let's underline the advantages. It goes without saying that this college is internationally recognized in the fashion industry, with a 100+ year history to boot. This is reflective of the continued standard and exposure LCF receives at the London Fashion Week. In addition, the frequent collaborations with corporations and household names in the industry are yet another indicator of its relevance (recently with the Beijing Olympics and with multiple high street chains such as Topshop and River Island). I regularly visit and observe catwalk exhibitions throughout the year (as part of my job) and LCF has continually impressed me overall. To be fair, aside from a select few other institutions, there's not many "good" fashion institutions in this country.
Another thing to bear in mind is that the college encompasses a range of courses that all vary considerably. The tutor(s) and the 'type' of students you will encounter depend on so many variables that it's difficult to generalize. Although I studied at CSM (an associate college within UAL), I visited LCF regularly due to friends. The stereotype that people are obnoxious is overrated. I certainly didn't experience this, but I won't dismiss that it exists.
In essence, LCF has its downers, absolutely (akin to the rest of UAL), of which I won't list because you're not seeking that. Ultimately, self initiative and natural awareness of the industry you're trying to get into is imperative. Students enter the college with an element of naivety and expectancy that just because it's LCF they will receive everything on a silver platter. As notdellie has rightly said, with all of these art and design colleges, what you receive is what you put into it. Opportunities are abundant to those who seek it.
Also, don't base your opinion from an internet forum, of which very few are actually students from the college (went to an Open Day or viewed some newspaper statistic). Your decision should derive from the standard of the work the course is producing (shown on the website and/or yearly degree shows) and by visiting the college and speaking to the tutor/students yourself.
