I don't think there are a lot of Spanish restaurants in Jakarta and to narrow it down even more: good Spanish restaurants in Jakarta! Plan B, Javanegra & Por Que No are some of the good ones that pop in my head if you spontaneously bring the topic, anyway recently I was invited to have lunch at this restaurant that I've been wanting to go but haven't got the chance (and now finally did!) called Tapas Club, this franchise is originated from Singapore (and they also have one in Malaysia) and their Jakarta branch is located at Setiabudi One precisely next to St. Ali!
