This real estate report says this building was built in 1986 -- I would have guessed a bit earlier than that. I was first aware of it when it was a Garcia's Mexican restaurant. I'm pretty sure that this was the spot anyway, though the facade was different (the real estate link says the place was remodelled in 1996..). As I think I've written somewhere, Columbia has a hard time getting and / or keeping "national" Mexican chains. We never had a Rio Bravo, Chevvy's, Chi-Chi's or On The Border, and we lost Garcia's and Don Pablo's. El Chico seems to be the only one that sticks. To be fair though, I think the whole Garcia's chain has fallen on hard times, and they closed their Myrtle Beach location several years ago.
After Garcia's the place became Roadhouse Grill which was sort of a Western place like (but not as good as) The Texas Roadhouse on Two Notch, but that didn't last long either. After that I think the building was empty for several years until it's most recent incarnation as a Bingo hall.
UPDATE 13 May 2010: Just for grins, here's the old Garcia's building in the Kroger plaza off of US-17 in North Myrtle Beach:
