Saints fan Bar in North Baltimore
Hey Scott, I don't think it is specifically a Saints bar, but Mother's Grille in Federal Hill is (soon to be was) opened by a guy from NOLA and he is a big Saints fan. I met him a few years ago when the Saints were here playing the Ravens.
It was recently announced that they will close in January, but it's a pretty cool place.
Let me know if you don't find anything and I'll see if I can dig up anything else. My son also lives in Towson. Is yours going to college there?
