not that anyone in wichita seems to give a -----, but the best strictly Thai food I've had (and i think i've now hit 'em all) is Asia Garden on E 31st at Hillside (the Tha-Lao Cafe down the street is still my "best" SE Asian food, but it is more Lao than straight Thai). Have eaten there a few times now and each time it seems to get better. The owner is a long-time chef, she is of Pakistani-Chinese heritage, but grew up in Thailand, maybe she was born there. Anyway, she will spend hours at your table talking about food, showing ingredients, and explaining the food. She is delightful, though a bit hard to understand all she says.
the green curry is the best in town. no question. and unlike many places, she hand grinds her curry paste (thai curries are all different requiring unique combos of herbs, chiles, etc. she does hers the "real" way in a mortar and pestle. she offers a couple of Indo-Pak items as well. can't wait to try those.
the num tok, beef salad, is astonishingly flavorful with lots of lemongrass, chile and other flavors beaming from each tender piece of perfectly cooked beef.
they offer 10% off right now if you have some types of affiliation: WSU, military, etc. My first time in, she gave me a hand written coupon for 10% off my next meal.
oh, if you get the green curry, ask her to use Thai eggplants in it...she has them but only includes them on request...
this place really rocks. too bad it will remain a secret
