Yes in fact I've done 2 reviews now of TGIFs. Their first one (pre-Atkins-Menu) was pretty bad, we even went there a few times and were reminded each time of how bad the menu was. We've been twice post-Atkins-Menu and I have to say that I agree with you that it is "OK". I wrote it up here - http://www.bellaonline.com/articles/art15597.asp
but in essence the items on the low carb menu are the same as on the main menu (for most of them) and in fact in some cases you pay MORE for the low carb menu version for no reason. For example, on one dish they simply remove the mashed potatoes - but they charge you the same price. In any case it's nice as a publicity thing, to show non-low-carbers that this is "normal yummy food" that we eat. But as far as really offering low carbers something "special", all they did was reshuffle their menu <img src="/images/graemlins/smile.gif" alt="" /> .
On the other hand I am VERY impressed with the Subway wraps. I think that was brilliant. I used to love going to Subway and was really sad when I had to stop on low carb. Now I can go again and get all the different meats on a healthy bread. In fact we were at a subway in a mall a few days ago and 2 out of the 3 people in line ordered the Atkins wrap. So it is HUGELY popular. Now THAT is a case where they really did do something special for low carbers that was of great value.
