With the promise of a much greater choice then your average burger bar, and a good flame grill sizzling in sight, it's easy to hope for too much here. FBC is another me-too following in the footsteps of GBK, but manages to fall short. The ingredients are there, but just not with the attention to detail to pull it off: great flame grill - but the rare burgers came in 'blue', lazily turned, barely singed on one side (and the meat not good enough for a steak tartar by a long way); good baps with generous doses of grain showed the buyers were trying hard - but served very cold on the underside and no attempt to properly toast them (classic for mass production straight-from-the-fridge set ups); tomato relish so mass produced and cheap it's really worth skipping. That said, the kids' mini burger selections looked fun and a cool way to make an adventure out of a burger, the wine selection was surprising, and the range of lamb and chicken burgers is refreshing. The 'breadless burger' came up trumps with a good salad and oil if you asked. Overall? Many of the right ingredients, but sloppily executed leaving us sure to head over the way to Nando's the next time we needed a protein fix before the movies. Like a bright kid at school who can't be bothered to get off the couch: 'C- ...underperforming, wasting, could try harder.'

Deep in the Polanco district of Mexico City you'll find one of the swankiest hotels in Latin America, equipped with one of the funkiest restaurants. The rooftop terrace is the perfect place to enjoy your burger and fries; and the cocktail bar downstairs the perfect place to go as the party gets going.

Awesome. A gem of a grill that's just opened in West London. It's only one of a pair and based on the first three visits there will be many more on the way. These guys will live and die by their burgers so the meat is excellent, but their owner has gone out of his way to source some great bread (light, moist ciabatta) and fool around with some interesting sides (not sure the courgette fries will be for everyone, but it's cool to see options like that). Thing is that their super hot charcoal grill really sears the burger in the way you can only dream of. This could be the Ultimate rare burger in London. And where they also excel is on the dips: there's half a dozen home made dressings that really are made on site - my fave is the stilton, but don't dismiss the bbq or the tomato; both outstanding.

A classic London stalwart. Tootsie's was a regular weekend treat of mine as a kid and I've still got a soft spot for this place. Generous burgers, heaps of relish, and a suitably tempting array of breakfast options are enough to make you loose a Sunday morning, afternoon and evening if you're not careful.

Not a good day for the chains. Hamburger Union has developed a pretty solid reputation, but it's only as strong as their last customer experience, and today was a pretty poor experience all round. How any manager can think of getting away with grumpy and rude waitressing staff is beyond me, even if they rely on a casual and not repeat trade. It only needs one sour apple to turn the keg bad, and maybe that's why there was a chronic inability to get orders right and a reluctance to apologise. In the world of burgers the difference between the well-dones and rares is a gulf and this branch gets struck off the quest for the Ultimate Burger for sure.
