Baan Suan is a popular Thai food restaurant in Mae Rim.  A lot of company groups and large families eat here, and it can handle a crowd.  Parking is ample, seating is spread over several levels, and the kitchen is large.  The dishes are all the Thai standards, focusing on fish.  I especially enjoy their Fried Fish with Chili Sauce, but the non-seafood dishes are also good, especially their Paad Krapow Moo.  Service is good, and the prices are reasonable, so it’s a good family spot.  Most of the seating is outdoors, but there is a small enclosed and air-conditioned space if required.   But given the usual evening Chiang Mai weather, this is usually unnecessary.  Just make sure to bring along the bug spray!
