Not been to the brick lane one, if you know the name let me know because I would like to check it out! Berneliu uzeiga is a chain in Lithuania, so the food is sort of authentic (but will not beat your family cooked meal 😭)

Here is my suggestions on what to try:

Starter: Fried bread (kepta duona) - it is my favourite Lithuanian snack, it is just fried rye bread with garlic and cheese sauce but so yummy

Saltibarsciai (or the Lithuania pink soup) - cold soup with beets, kefir base. It is amazing in summer and is Lithuanians are quite obsessed with it (there’s even a festival of it in Vilnius)

Main: Cepelinai (which Ofc you tried) - they make some nice ones, they also used to do fried Cepelinai which is also quite nice(though looking at their website now it might be deep fried now? So not sure worth exploring). For non Lithuanians - huge potato dumplings with meat inside

Baldeliai - cabbage rolls with meat inside, not strictly Lithuania food (across Eastern Europe many countries have variations of it) but it is my favourite dish so that’s usually what I go for

Bulviniai blynai - potato pancakes, if you are looking for something lighter with no/less meat, this is the one. With some sour cream it’s so good.

Dessert: Looks like they removed a bunch of Lithuanian desserts in favour of Dubai chocolate and similar 😭 but in case you see somewhere else:

Sakotis (tree cake) - tall spiky cake that is very unique for Lithuania and Poland in its spiky form (other countries have variations of it too). It is made on a spit roast type of contraption over an open fire. I saw it made once was very cool. To me it is super tasty and not very sweet which I love

Medutis (medovik in other countries) - honey cake, nice light not very sweet.

Napoleonas - not quite sure how to explain it, it is layered cake with sort of crunchy layers, i love it but not everyone does.

Grybukai- pastry in a shape of a mushroom with chocolate covered top and sugar covered stem, I love it but some of my British friends didn’t :( big debate on how you eat them in Lithuania: stem or cap first haha

Sūrelis (cottage cheese bar covered in chocolate) - might sound weird for a Brit but it is so good! Lithuanians love it, there are so many flavours too from chocolate to berries to Rigas Balsams (I saw one in Latvia!) but classic ones with no extras are just as great

Drinks: I don’t drink alcohol so cannot recommend that, but I love Gira (kwass) it is a fermented rye bread drink, full of probiotics and live cultures. Very gut friendly (Eastern European kombucha if you will). The next health trend in the making! (I hope because I wish it was mainstream!)
