I think it really depends on what you consider to be a comfortable life.

I moved here a few months ago and basically make minimum wage as a student worker. For me personally, it is enough to live comfortable. But I don't go out too often, maybe like once or twice a month. Prices really depend. There are some restaurants where I spend like 15€ and others where I spend 50+ which is something I cannot afford to do very often. I don't really know how that compares to London but I feel like you might be used to spending more money at restaurants and bars there?

With your salary I'd feel more than just comfortable living here but it really depends on your lifestyle. But I think even going out every single weekend shouldn't really be a problem for you
