I'll take a crack at this, as a fellow foodie.
Went to Tchoup Chop about 2 weeks ago. Had a 6:30pm reservation, kept waiting at the bar for a while so I had some time to look around.
Atmosphere: The decor of the room is quite nice, with mosaic on the walls and a lilypad fountain in the center. The room is not partitioned, but not overly loud. There is also bar style seating along a window looking into the kitchen which can be interesting if you are into watching food preparation. Mostly adults, but a few kids with families noted, but definitely a more sedate crowd.
Appetizers: Shrimp Crackers are served with a peanut dipping sauce instead of bread. If you had these when you were a kid as I did, you think they are fine. If you didn't, well... let's just say it's an acquired taste. The actual appetitizers are competently done. My wife had a lobster appetizer that was the special that day, which was quite good. The crab cake I had with a papaya salsa was also nicely done, though a little over garnished.
Entrees: My wife had the Hawaiian Style chicken which she pronounced flavorful and moist, but I could tell wasn't blowing her away. The sides that were served with it though were beautiful and done perfectly. I had the claypot of the day, which was a concotion of rice, and various types of shellfish and fish, in a coconut milk base. Think of it as a non-spicy curry I guess. I got it because I thought it would be interesting. I guess I would say that I was slightly disappointed with the texture of it, as I would deem it on the soupy side (much more so than a comparable gumbo in my opinion). Still, the seafood was quite fresh within it and it was very good, though not quite excellent yet.
Dessert: We shared a pineapple upside down cake which was excellent as well as some sorbet which was also excellent.
Service: Service is performed by a 3 person team. They were very attentive with refills, etc. and checking in, although you could see that they were breaking one of the people in I believe, who was getting instructions.
Total bill: $92 for food and tip (no alcohol that night) for 2
Overall: I'd say that the restaurant has the potential to be excellent but isn't quite there yet, and a notch below Emeril's in Citywalk where I had an excellent lunch on a different trip, and a larger notch below the Emeril's that I went to in New Orleans in the Warehouse district. The room makes for a nice experience, but the food is still a little hit or miss. That being said, it was still a worthy attempt and I'm not sorry I went. At $45/person for 3 courses, I thought it was reasonable but still felt that I was paying for the Emeril name (in other words, over-priced for the quality and composition). To be honest, I enjoyed my meal foodwise at the Brown Derby in MGM more approximately the same price, which really surprised me (maybe because I have lower expectations for food inside theme parks?) as well as at the California Cafe which is in the Florida Mall (don't be put off by the mall setting, the food is actually very good!)
Note: I also tend to be harsh on restaurants, as my favorites tend to be in the high end range ($60+/person for food) so your mileage may vary. Also Pacific Rim Fusion and New Californian are my two favorite restaurant types, so I have even higher expectations when it comes to those. For a comparison in this realm, I'd say that Roy's does a better job of this in the chain department than Tchoup Chop did, in general (haven't tried the one in Orlando so I can't say specifically in Orlando whether this is true).
I hope this helps you. I'd say, go ahead and go, it's a very good meal at a high but not ridiculous price. However, if you really want to get a sense of Emeril's cooking, you are better off at Citywalk, as that is much truer to his New Orleans roots.
