Went here this past Saturday with a girlfriend of mine. It was our first time (someone recommended we go there) so we were a bit shocked when we walked in at how small it was (there is a back room but I never went back to see what's it like as we got last 2 chairs at the bar).
Perhaps Ronnie's is often visited by either more of a regular crowd and/or "dive-y bar looking crowd that the two of us stood out and were approached by both men and women a few times during the night. Flattering and bizarre at the same time.
Prior to going, we read a few not so flattering reviews on this place due to bartenders attitudes but they were really nice to us. We decided that we will definitely be going back to this place.
