In terms of "LCN-wise" there is really not much. As mentioned, Ybor City is the historical stomping grounds of the Tampa mob, and a few places remain from the old days, such as the Columbia Restaurant(Trafficante's favorite restaurant, but that area is now mainly ghetto, and the historical 7th ave strip is a bunch of night clubs, etc. But as mentioned, very cool place to visit in the day, however might not be your type of place at night unless you are younger.

Another place you might wanna check out is the Tahitian Inn on Dale Mabry, old hotel owned by an associate where meetings, etc., used to go down. If you are looking for more recent places, there is the Mirage nightclub on the corner of Himes and Hillsborough. The manager there was some Gambino associate who was indicted a couple years back alongside Gotti jr., believe his name was Cadicamo. I was suprised when I heard this because the club is a ghetto shithole, to put it nicely. Very ghetto, constant fights and several shootings in the parking lot, so obviously I wouldnt recommend going there either, lol.

Sorry I couldnt be of more help, but truthfully, I think what youre looking for no longer exists for the most part.
