Visited this restaurant with a large group celebrating a birthday, lucky for other diners they have a separate room for large groups which would help to keep the noise down for couples having a romantic dinner.
They have an extensive menu with all the standard Thai dishes - Pad Thai, Red Curry etc. None of the dishes I tasted were very spicy or hot, so it seems the spice level has been adjusted for local tastes ie very little spice. One particular dish we liked was the Duck in Red Curry, very good indeed.
They also have pretty good drink list including wine starting from about $30 per bottle and a range of imported and local beers.
Over all Lanna is a good restaurant without anything to really excite, anyone eating here should leave happy that they had a good meal at reasonable prices with very good service.
