Dim Sum is one of those things that often come at a premium price, especially in Chinese restaurants or at 'Dim Sum Lunch Buffets' at hotel restaurants. Just recently I read an ad in a local Thai newspaper about the 199 baht dim sum lunch at the Empress Hotel.. May give that a try sometime, as I'm still looking for 'really good' dim sum. I only found out how good dim sum can really be when I went to Hong Kong, and sadly I've never found anything in Thailand that gets close. Very close indeed got the up-market Chinese Suki restaurant that I reviewed http://chanchao.fotopages.com/?entry=109742(here), though the owner told me he will open a dedicated dim sum place at the Airport Plaza mall and stop selling a big variety at the main restaurant. That one is on my list as well.
Until that time, let's settle for 'pretty ok' dim sum but then 'really cheap'. 8) This can be found at this shop, 'Toey Dim Sum' (no English sign) on Kamphaeng Din road. The basic stuff like 'khanom jeeb' dumplings goes for 10 baht, the rest for 15. The bill for what you see pictured above came to 55 baht. The setting is of course rather basic, with a small shophouse restaurant area inside, and a wood & thatch road-side area outside. I think it's open late, so a nice stop on the way home after a late night out. Another place that's good for a late night meal that (also) has dim sum would be Aong Thipparot noodle shop on Phrapokklao Road, just South of Chang Phuak Gate opposite the Shell gas station. This is a very popular place for noodles in the evening and late at night.
Toey Dim Sum is on Kamphaeng Din road, the stretch SOUTH of the intersection with Sridonchai road. You will find it on the left side of the road.
