You can order the pad Thai if you like, but cliché noodle dishes aren't the best use of your time in this Richardson Thai restaurant. Bambu focuses on Isaan-style cooking from northeastern Thailand. Be careful. If the crying tiger beef can make a big cat weep, it can do a serious number on your own capsaicin receptors. You could order fried rice or a bowl of tom kha gai that will warm your center, but you're better off with yam pla duk fu, a honeycomb-like pile of catfish floss set atop a salad of leafy greens, slivered carrots, red onions and peanuts. Fish cakes, fried tofu, deep-fried soft-shell crab and more round out a line of authentic Thai pub grub that will keep you smiling for hours — especially if you supplement your meal with plenty of Singha.
