As I stepped through the doors I felt like shouting “Zulus, thousands of 'em” only it's not African warriors it's children (scarier). Still, you shouldn't go to feeding time at the zoo if you don't like animals. According to the marketing spiel the idea behind Byron was to create a restaurant serving simple, tasty burgers as there weren't any doing that. Perhaps the founders hadn't noticed the explosion of GBKs, Hamburger Unions, Fine Burger Cos and the general slow but inexorable culinary rehabilitation of the hamburger into civilised society. Anyway, my hamburger was perfectly edible but perfectly forgettable. The venue is bright, cheery, clean and the waiters are doing an admirable job of waiting/nannying/cleaning up the devastation whilst smiling. It's basically GBK with more floor space and a more mature typeface.
