100% agree. Why go somewhere new if you like where you are/ what you eat etc?
I stopped going to different countries after I discovered Thailand, except for one mistake to Sri Lanka. Didn't like it at all, and stuck with LOS thereafter. Perhaps I missed out on some great experiences, but that I can live with, though perhaps I should have made the effort to see Petra.
As for eating, I mainly ate at Geckos in Chiang Mai. Not the best decor, but the food was great and the waitresses friendly. I did try Dukes a couple times, but too expensive and the food didn't taste any better.
So, basically, if it ain't broke, don't try to fix it
