I love this little stall in St. George's Market and get my breakfast there every Friday (and sometimes I go on Saturdays and Sundays as well)! Most things are vegan and/or gluten-free and they are all labelled so it is really easy to find out quickly which things don't contain dairy or eggs.
My absolute favourite is the chocolate donut with salted peanuts but I have tried almost all their donuts and tray bakes and like them all.
I usually buy some for my boyfriend or my meat-eating colleagues as well and they all like them too so this is not only for vegans/ vegetarians.
Most things are £1.50 each or £5 for a box of 4.
