"The burgers at Bun & Sum in Hackney Central are worth travelling for and are some of the best in London. Smashpatties are stuffed between soft buns, topped with brisket, pastrami, or a slice of american cheese. Persevere for a stool—these excellent burgers are best enjoyed freshly smashed and sizzled, while nodding along to the bumping hip-hop/R&B playlist. If you want it to takeaway, their original Mile End location is better." - rianne shlebak
