The best cakes come from Lucy's bakery. When I was taste testing for my wedding, theirs was the most moist and most reasonably priced. Best sushi is Sushi Zushi, but it's a little pricey as you know sushi con be. Last time I ate at ChaCha's, there was a dead roach on the floor next to the table that we didn't discover until after we ate. Chris Madrid's tastes like Whataburger, and I think Whataburger is cheaper, not saying that either are really something to write home about. Chris Madrid's has just been around a while, so it has that gossip effect, if you know what I mean. Best Chinese is probably PF Changs. A chain, but good. Pei Wei is owned by PF Changs and is also good. Never eaten at Florio's or Zito's, so let me know how it turns out. Luce, at Huebner Oaks, is probably the most authentic Italian and my husband is from Italy. It's a little pricey though.
I'm from Houston and there are great places to eat there, so as you can tell I'm a little disappointed w/ SA food, but good luck to you and happy eating.
