When your options are limited, as they are in the US section of Terminal 3, TGI Friday's is a like an oasis in the middle of the desert.
There are not a lot of eating options near the "A" gates and since my first flight got can celled and my second was delayed, I had time to kill. Plus I was hungry and this was about my only option.
The server was very nice, although a little chatty. I'm not looking to be anybody's best friend, I just want my meal. She sold me on the large margarita which was weak (and at $14.99, more expensive than my food!). My bacon cheeseburger (with American-style bacon, even though I was totally still in Canada..what a ripoff!) was over-cooked but still pretty tasty. Fries were good.
All in all, it wasn't awful.
