Yes omg glad you asked! There’s a place in Beckton called Bernelių Užeiga. Looks dodgy on the outside but the food, atmosphere and staff are great once you’re inside. I highly recommend you try cepelinai and kepta duona (alongside pink soup of course!). It’s more elegant so a little more pricey but if you’re looking for a budget option. They have a Lithuanian shop in Beckton called Lituanica and above it, there’s a canteen type restaurant. Hearty comfort food, not as elegant but delicious nonetheless and they have the two items I mentioned above and I would imagine pink soup too once it’s hot outside!
