I was planning on showing Southern Thai food today, but still no luck finding a place that's really exceptional in that area in Chiang Mai.. Stay tuned for that one. So instead let me opt for the best Ice Coffee in Chiang Mai. 8-)
Most of the time when you order coffee in Thailand you will be served Nescafe instant coffee, with some Coffeemate creamer. This is changing now with more and more 'real' coffee & cake boutique shops opening up. But Thailand has always had places selling real coffee, often very strong and sweet. This is called 'Kafae Thung' (coffee from a bag) or 'Kafae Boran' ('ancient' coffee, or old style coffee). The bag here is a cotton re-usable filter that's used to make filtered coffee.
It's less sophisticated than the new air-conditioned Starbucks copy-cat shops, but definitely worth trying, and also quite inexpensive at 5-10 baht for a cup or glass of hot or iced coffee. Thais do like it sweet though!! :-D
Old style filter coffee can be found in many places, often near markets or food markets. This place is located outside a curry & rice restaurant on Charoen Muang road, on the right side before you get to the railway station. It's just after a Shell Gas station. You can order take-away in a bag with ice and a straw..
