'The best burger on the high street’ & other superlatives are regularly tossed in the direction of Byron Hamburgers, the chain that even hipsters will admit to liking. There’s nothing ‘flash or clever’ about the concept; it’s all about ‘honest, juicy burgers served medium with a proper bun’, plus fries & ‘damn fine’ milkshakes. Gourmet twists are notable for their absence, though specials surface from time to time – note the cult favourite Big D & the Uncle Sam with a glazed bun & American cheese. The attention to detail extends to the rest of the offering, including US & British craft beers, soft drinks & decent coffee. Ambience can be anywhere on the mood spectrum, from ‘pleasant hubbub’ to manic. Service puts far posher places to shame.
