Is there also a bus from Macau Tower to Fernando restaurant (in Hac Sa)?

From the Tower, you can walk about 100 meters to reach TORRE/ TÚNEL RODOVIÁRIOS where you can find bus MT4 to take you to reach POSTO FRONTEIRIÇO DE COTAI. Then you need to walk another 100 meters to reach POSTO FRONTEIRIÇO DE COTAI. There you can change to bus 15 to take you to reach PRAIA DE HAC SÁ.
Then you can walk to reach that restaurant.
