hi,me and my partner are staying 3 nights very close to regents park ,albany street,I have booked tickets for a rib ride,hms belfast and madame tussauds,Are these places walkable from that area or will we need the tube /bus? Also someone said for us to go to borough market ,is it worth a visit? we are not london savvy having only been there once before !!! We will be there on a saturday afternoon ,sunday and monday.Any help would be grateful thanks.
