Go to Lao Sze Chuan. Order Boiled Beef and Ma La Spicy Chicken Pot, and tell them "full Szechuan spicy. No. Seriously. I want it all the way spicy."
Don't eat any rice. Then, go over to Birrieria Zaragoza for the bhut jolokia
salsa de molcajete while they still have the peppers. No Mexican coke.
Close with Suicide Wings at Jake Melnick's if you're a yuppie, or dhal and tandoori chicken at Rajun Cajun "with the really hot stuff, black bottle" if you're a hipster.
Antonio at Xni-Pec also has several things that can dissolve your soft palate. I'm shooting here for things that are reasonable food in addition to sheer Scovillemanship. Enjoy.
