A guy asked me out to dinner but never said what restaurant… the date is in 2 hours

He slid into my instagram dms last Sunday and asked me out, we talked for a while and he asked me to get Puerto Rican food with him. Then he said he didn’t know where to get it so I said I was open to anything Latin American. On Monday he said he knew a taco spot but didn’t know the name and would find out and let me know. I asked him what day and time worked for him, we agreed on Saturday. On Wednesday I realized we hadn’t finalized a time, so I asked. He said “idk probably later, like 6?” We agreed on a time and he said he’d be looking forward to it.

It’s Saturday night, the hour is approaching, and I realized he never even told me where we’re getting food. We haven’t talked since Wednesday afternoon. I don’t wanna go out with this low-effort dude anymore, what do I say if/when he bothers to message me the place?
