Touich has made its name on good food and friendly service. The location is obscure. There are no walk-ins. The decor isnâ€™t anything special either. But most nights, itâ€™s busy with expats and tourists heading away from Siem Reapâ€™s tourist heart and into the darkness to sample its fare.Â Touich is a simple but very popular family-run Khmer restaurant thatâ€™s a little out of the way but worth the effort.
