Since I'm in Midtown a lot more these days rehearsing for Fiddler on The Roof, I've had opportunity to check out Soul Fish on a number of occasions, and sample a little of everything on the menu:
Sandwiches: The Cuban is excellent--there have been a couple of places in town where you could get a decent cuban (Sabor Tropical on Lamar, which I think is closed now, and Bahama Breeze). The Memphis is outstanding. Both of these could give you a heart attack if overconsumed.
Catfish: I've had the catfish appetizer, and if the regular catfish compares, it's really good. The slaw is also excellent--a little sour, a little oniony.
Chicken: The smoked chicken is very good, if a little dry the time I had it. Kinda a dry ribs version of chicken, it might benefit from a little available sauce.
Bonus--you can substitute a vegetable for fries with your sandwiches, which is good because some of the vegetables are excellent, whereas the fries are merely adequate, and not worth the calories if you're wathching calories.
Also had the deep dish Chicago pizza at Jimmy's in Bartlett. It's very good; two and a half inches thick, sauce on the top, crusty, chewy crust, loaded with toppings. The 9" small will feed four EASILY.
That said, my personal preference is for the thin crust Chicago pizza there--the deep dish is a little too much of a good thing. But if you're in the mood for real Chicago pizza (thick or thin), you should check it out.
Now I need a salad.
