I'm not familiar with places like this at all, so I imagined more of a shop with shelves than a cafe. But I have to say, it turned out to be very atmospheric, and what a view from the window! You should just play The Lord of the Rings. In general, I'm surprised how you found such a great place, but the combination with a cafe is definitely a plus.
By the way, have you already put up posters around the city? I can recommend A6 stickers, and also print some small A4 posters – the more, the better. And put them in places popular with young people: bus stops near universities, shopping centers, ice rinks. You can also put information on bulletin boards in universities, and on buses using self-adhesive stickers... self-adhesive stickers are the best because they are thin and hard to peel off, unless you peel off your nails along with them. But the downside is that they don't stick in the cold, but the solution is simple – stick them on with water! (or frost-resistant glue for normal people).

Great photo, it would work well for an advertisement, but only for a school. To hang it in universities, you need to take a photo of a close-knit group where everyone is hugging and smiling in front of the window – that would be a great idea. So, send me photos if you have any, and I'll help you with the design, for example, with the text composition
