Good Morning Kynsley,
Welcome back to MS. I didntknow Bubba Gump had closed, but is no surprise. I ate there one time and it was like eating at Captain D's. Not very good.
I really like Cajun Crawfish Hut in Long Beach on Hey 90 @ Cleveland Ave. The food is really good, as is the price. Just the right amount of spice without being too spicy. Some of the best gumbo I have eaten, IMHO.

As far as beignets, Triplett Day drug store in downtown Gulfport makes them. I haven't tried them myself.
