Its just a time to meet new people and to have a little fun on saturday afternoon.
The topic is simple - English speaking and to get to know other English speakers.
It is also not important how good is your English - just a beginner or a native speaker, because all interested persons are welcome. I myself cant say I can enough English to speak fluently.
Because we will sit in Cafe, you must be ready to pay for you a cup of tea for example and also you must be already 18 years old.
