"Medium" isn't a server's suggestion at US Thai Cafe when a new guest innocently asks for Thai hot -- it's an order. Because US Thai's "medium" is what most places peg as "hot," a sweat-inducing smattering of fiery red chiles mixed through any dish on the menu, used with just enough restraint to allow an eater to actually taste the rest of the flavors in the excellent food. But for those thrill-seekers who crave insane levels of heat, the kitchen will punch up everything from the green papaya salad to the curry with angry-looking peppers that are probably hot enough for some sort of eating contest, guaranteed to blister your esophagus and make your adrenaline flow.
