This contemporary Thai eatery in an updated glass-sided 1970s house was the hottest star in the firmament of new Chiang Mai dining experiences. Dalabaa owes much of its unique charm to its fabulous setting, with echoes of art deco, Frank Lloyd Wright and Feng Shui woven artfully in to the modern design and decor. Stark, sophisticated geometrics are balanced with sumptuous shades of crimson and vermilion.   Service is average, with attentive, but not overly efficient - nor trained - staff, dressed in elegant contemporary Chinese outfits.
