Certainly looks like the seaside, with those people leaning on the railings. The presence of charabancs outside the building adds to this impression. The clothing suggests a holiday town - panama hats on the men and the main person wearing what would have then been casual clothing - blazer and open-necked shirt.
The poster on the notice board looks rather like an advert for a theatrical performance, but I can't read either the poster or the lettering at the top of the board. Behind the man I can read "Post", though not "Post Office", which is what I would expect to see in England.
The style of the buildings suggests the South Coast to me, with the Georgian-style balconies like Brighton or St Leonards. It must be quite a large town with buildings of that size and a busy one, too, from the number of people about.

Added later - Actually the balconies look as though they are made of stone, rather than the Georgian metal ones.
