i've been back to thai basil a couple times in the past month after dropping them from my "places to go" list a while back. they've turned up the heat a bit, and the food is improved. they're actually serving food that hits the bottom end of my hot/spicy register (that translates to "how the hell can you eat this?" for most people). it's still not what i would really call hot, but it's a vast improvement. you have to ask for the heat, but they will give it to you. the dish i've been experimenting with is the kung ka-pow (various vegetables including jalapenos, your choice of protein, specify the heat).
