This is the first Hard Rock Cafe located in London. I have noted the location on the map below. Not far from Buckingham Palace and Piccadilly Circus
Definitely an American magnet because they serve Bud Light and other US beers. Only place I have ever seen Bud Light in Europe. Kind of funny when you are a craft beer guy. I did take a video of the inside and my wife had the coldest Stella Artois she has ever had. Definitely a good stop for a pint and maybe even some food if you are in the area.
