Karate/Judo/ Taikwondo (Lisbon)

Hello all,

I have not quite decided which martial arts to go for but would like to take up lunch time lessons in either karate, judo or taikwondo. I work in central Lisbon, Avenida da Liberdade, and would prefer to take classes during my lunch break rather than after work as I live about an hour away. I do not want to join a fitness studio for this and would prefer a pure martial arts organisation.

Does anybody have any pointers for me?

Many thanks and have a great day.

Jona
