Since you are there you might as well try some Chanpuru. It is a stir fry dish with Goya but it can be a bit strange for first timers. Not sure on what’s there anymore, been 15 years. Yoshihatchi is probably still there, pretty good sushi joint.
I also recommend that you hit up Peace Memorial Park if you can make it down to the south side of the island. Can’t remember if the tunnels are near that but those are interesting as well.
Same here. 300w with 12 disks, switches, and router. But electricity only costs $.12/kwh. I wouldn’t trust having terabytes of data in the cloud.
