Bangkok hounds, thank you so much for your help so far! I leave Bangkok tomorrow evening and I've had such a great culinary experience here that I thought this might be the place to get a gift for a special foodie in my life. Unfortunately he is quite possibly Chowhound-stalking me, but that's a risk we'll have to take.
What neighborhoods/markets are the best for cooking stuff? I went to Chatuchak Market and managed to get myself a mortar and pestle but then was too exhausted to shop for anyone else. Then I went to Aw Taw Kaw Market and ate everything that I bought. Tonight I headed over to Soi Pradit Market because Lonely Planet (I know, I know) said it was good for cookware, but it was already pretty dead by the time I got there at 8.
Any recommendations for interesting food gifts or nice cooking equipment? Something not too large would be ideal, and also something that doesn't already exist yet because he already has everything that could possibly be used for anything cooking-related.
