I've always been very impressed with TGI Fridays - I'm honestly a very fussy eater too. I've been to places and ordered food and walked out when it's arrived. We once got a little square of clingfilm in a burger which was used just to separate the burgers in the kitchen. Complained and they gave us the entire meal free of charge! There were 4 of us there and we'd each had a 3 course meal! A bit OTT I thought, but hey you certainly can't complain!
I've also been in there before and ordered a side salad and then been so overwhelmed with the amount of food you get that I've not eaten it and then the waitress has taken it off the bill at the end. Really good service. I don't really like Americanised companies and it doesn't get much worst than TGI's though.
Very few chain restaurants impress me. I quite like Nando's too.
