To Be Honest, i don't like the weather of UK, i know it is quite straightforward but everyone agree with that! so the environment of place could be very important factor due to bad weather(bad weather could make you feel depressed !! seriously)
see! i took above picture in the city centre. as you can see, many people can easily find some places to relax even middle of the city centre ! actually this is one of my favorite places :)
Birmingham's Frankfurt Christmas Market is obviously enjoyable for everyone!!(it opens now until 22nd December ) you can feel the Christmas in this lovely places!! Christmas carol, exotic foods, coffees, mulled wine, fancy chocolates etc..
Definitely, you are not gonna be easily depressed due to english bad weather(or foods) in Birmingham!! there are lots of enjoyable events in Birmingham including Frankfurt Christmas Market
