BG Zakuska Bulgarian Breakfast is a small chain of cafes/bakeries with branches around London. Food is limited to sweet and savoury pastries and “rolled pizzas”, cold or heated in a microwave, for eat-in or takeaway.
My cheese and leek banitsa from the Barking branch (46 Longbridge Road, IG11 8RW) tasted freshly-baked, with soft layers of pastry enclosing salty white cheese and leeks cooked to a gentle sweetness (photo once taken home and sliced).
Just a quick update on this one — they do hot food now as well. The options change, but the last time I was there they had chicken and rice, lamb with potatoes, moussaka, tripe soup, and zelevi sarmi (pork/rice-stuffed cabbage rolls made with pickled cabbage). I had the zelevi sarmi (photo), which wasn’t bad but would have been better served hotter.
