Brunch. That immortal concept. £25 avocado mush on rye. Great meal, amazing meal. Sometimes though you just want something a bit more substantial without the commitment of trussing it up and labelling it “lunch”. And sometimes you just want something free. Honest Burgers knows this and has decided to mark the opening of its Baker St branch today by giving out a load of free burgers/brunch. All you’ve got to do is fill this form out. Which is very easy. But also limited, so be quick.
