This trip, Guy Fieri's livin' it up in London, digging into a real-deal regional feast. First, a couple of British buddies smoking up true blue American 'cue. Then, a hip hangout giving classic fish-n-chips a modern makeover. And Guy finds a taste of legit English fare at a locals' favorite, serving standout shepherd's pie, braised ox cheek, and righteous rhubarb cheesecake.
