You can try Impakt Singapore at Robinson Road, central Singapore. Its a MMA gym just like Evolve but they have a variety of martial arts like Muay Thai, BJJ, Krav Maga and their specialty french kickboxing, Savate.
Joined this gym about 2 months ago, it feels at home.
Prices are much more decent than Evolve.
Pm me if you need further info about this gym or you have any friends who are interested too.
