Question for the UK/Europe crowd,

I got a good friend that is always looking for business investments. Everytime we drink beer together he tries to convince me to get out of the Army and open ethier a saloon style bar similar to the ones I posted or a really over the top Texas BBQ joint either in the UK or in Europe. Basically he is a money guy and needs someone with experience running bar/restaurant establishments, which I did previously. He is convinced these type of places would make a killing. You guys think these types of places would be popular? I'm not going to partner with him anyway just curious if there really is a market for this style of bar/restaurant.
