If it is good enough for Rick Stein, it is more than good enough for us. A favourite of the best TV chef in the history of TV chefs, Casa Manteca is an absolute must-visit when in Cádiz. The interior is borderline thrilling and the authenticity of the atmosphere matches it, creating the right environment in which to eat seafood-heavy tapas that positively dances down your oesophagus. If you only get to visit one tapas joint in Cádiz you have probably gone wrong somewhere, but if that is the case then make it Casa Manteca.
