In Chiang Mai definetly less or same.
Once you get your restaurant/coffee shop network in place. Western food which I thought was 'same price now' as back home...indeed no...food in UK pubs etc up 50-100% in 10 years or so it seems.
Quality beer is only nasty priced thing here that springs to mind and Rimping foreigner back home type craving foods. You can get great craft beer in UK supermarkets 80 baht by local prices. Double here in supermarkets.
I mean, 'Cinema day Wednesday' or wharever it is called is about 1/10th of UK single ticket and the places are fresh withough nasty little chav culture disrupting the movie.
