There should always be fun!
Firstly and most importantly, English speaking clubs should be fun. If they aren't an enjoyable experience, then they are not being done correctly. You should look forward to them and they should be a place where you feel relaxed and not afraid to give or ask others for their opinion. Creating this atmosphere is really important and our host who is a British native speaker from England has over 10 years classroom experience and has become an expert in creating a friendly, open, relaxed atmosphere.
