C & C has a number of locations but they don't have the brand consistency you would expect. We also visited the main location in Bangkok and one other. We were brought here by our private tour guide and driver. They have a couple of lame older condom displays but it's kind of a half baked after thought. Our tour package cost U$900 a day not including international airfare so we expected the "included" lunches to be pretty good. The ambience is "truck stop diner", open with high ceilings and sparsly furnished. No air conditioning. They seated us by a window, which meant we got a nice hot and humid breeze, and plenty of highway noise. At least our sweat dried before it dripped in our food. The service is very basic, they bring your food and walk away, not exactly motivated. This restaurant exists entirely to serve tourists on tour buses. They have a set menu just for suckers like us. Sweet and sour pork and a fruit plate, this was the third "included" lunch in a row to serve the same food. The food was poor, not rotten or poison, but low on the quality scale for western standards. We refused the fruit plate desert because virtually every meal we had was followed by the same 4 or 5 fruits on a plate, breakfast, lunch and dinner. We asked for ice cream instead and offered to pay of course. They didn't have any! Actually just saying no and walking away. A hot climate full of tourists and no ice cream.... duh!!!
I don't know why I am writing this, tour companies rarely tell you where you eat lunch, and if they do most will look up the location in Bangkok in error. If you are on a $40 a day tour with lunch included then I guess you are getting what you paid for.
As we were on a private tour we had a lot of flexability. After this experience we just told all our guides "no set menu lunches, take us to the best restaurant you know and we will pay, we will skip the prepaid lunch". This worked wonders, even when they took us to the prescribed restaurant because nothing better was near by, they chatted with the managers and we got special treatment - a different menu than the other tourists so we could order a la carte and try some interesting local dishes, both only charged us $2 or $3 at the end.
