Customers can order from Lanna Thai's website and pick up their food or have it delivered in less than an hour. The cheerfully elegant space also offers eat-in dining. All the curries, sauces and other standards are offered for lunch and dinner, and beer and wine are served in the dining room. Lanna Thai is in the Arroyo Plaza shopping center near Las Positas and North Livermore Avenue; there's plenty of parking in front.
