Why do some guys put in mininal effort for a 1st date/meetup?

Today I was talking to a guy and we had some things in common. We both mentioned that we don't have plans tonight.. He then mentions that he will be going to a bar by his house for karaoke around 10 pm. First off the place is literally by his place, though we don't live far I would have to be the one to drive to at least meetup. I also mentioned that I quit drinking and he mentioned the food is good there.. Umm meaning I show up and pay for myself for bar food that may or may not be any good! I usually am in bed at this time, I never mentioned it. I had asked him prior if he wanted to go cycling, he didn't have a bike. Why such minial effort on his part? He didn't even offer a sooner time or to meet for coffee./tea prior.
