I've read all the previous posts and still need some direction.
I'll be in Memphis for two nights (on a Sunday and Monday).
I don't think I'll be free for lunches but will have two dinners.
One BBQ place and perhaps Gus'?
If not both of these places, what's a mid range priced place with music perhaps? Don't want fine dining but more of a fun atmosphere with good food.
If so, then you'll be right across the street from Corky's BBQ. Resist the temptation. Drive into midtown to Central Barbecue or the Barbecue Shop, or out to Germantown and eat at the Commissary for BBQ.
For non-chains in the area that aren't too pricey, check out Interim (sort of pricey - very good), Jarrett's (a little less pricey - still very good) or maybe (much more downscale) the Belmont for a fun place that I think is open Sunday night. If you're doing Gus', stick with the downtown location as opposed to Collierville.
I believe they have different owners, but for wahtever reason, downtown is worlds better.
