The positive comment I have about Southport Lanes is that the food, for bar food is good. Just good, not great. Also, consider yourself warned that Southport Lanes gets relatively crowded on Friday and Saturday nights.
As far as bowling is concerned there are much better places to go bowling in the city. I found the bowling staff rude and inconsiderate. The prices to bowl was ludicrous. In addition, the bowling portion of the bar is rather tiny. If you want to go there for entertainment, you are better off playing pool.
There are better bars to visit out Southport Ave.
