We had burgers and milkshakes in Koloa and the burgers weren't too bad, $4.50 for just a burger. Milkshakes were cold and nice.
We had milkshakes again at Bubba's in Hanalei, and they were warm and very disappointing. Stop by this place for the decent milkshakes. Nice spot as well. There is free wifi from the spot next door.
No wifi at Bubba's for customers it seems, so disappointing.
