That's right - Fagan's is right at the mouth of the river on the east bank IIRC. Might still be there. There was another bar along Old River Road, opposite side of the street. I can't remember the name, but it was there in the late 1970's / early 1980's and they did have live music. Things were a lot looser back then (notice, I said looser, not "loser" :-) ).
There's a place on the west side of the river, up a block or two called The Harbor Inn that had several dart boards upstairs and many brands of beer available. I wonder if they're still there. It was an older place, not one of the "touristy" places like Nautica or Shooters'.
Got kicked out of the Agora once. Well, actually, my buddies got kicked out and since they had the car, I had to leave as well.
I think the Harbor Inn stillis there.
Good times.....
Flat Iron, D’poo’s, thinking for more.
