At The Wing Dome, also known as the "home of the burn," you'll find wings that are straight "from the face of the sun."

This family-run, vegan Thai restaurant boasts some of the hottest dishes in Seattle. Try the Tom Yum Soup or the famous Drunken Mushroom Noodles, stir-fried with three kinds of mushrooms, garlic and chile. Roger Mooking says the noodles "start off smooth and then hit you with the heat."

Music and food go hand in hand at this cozy Southern soul food joint and music venue.

Feeling spicy? Try the chile-spiked oyster shooter, a "kicked-up" combination of oysters, horseradish and black pepper vodka. For dinner, there are plenty of mouthwatering, less spicy options, including lobster rolls, steamed littleneck clams in white wine and garlic, and grilled mahi mahi tacos.

The Hell Burger at Rooster's Roadhouse is so hot you'll need to sign a waiver before chomping down on this slider. Roger Mooking and Aarón Sánchez did, yet even these Heat Seeker pros reached for the ice cream. Luckily, Rooster also offers less-spicy barbecue, like pulled pork nachos.

Stop by Scoreboard for a full serving of sports and a devilish dose of "hot chicken" that will "blow your ears off," as Roger and Aaron experienced on Heat Seekers with Tennessee Titans safety Jordan Babineaux. The fiery chicken comes in multiple temperatures, from "sissy" to "Satan's Tongue."

A neighborhood bar-restaurant in Nashville, Mad Donna's is known for a great brunch and solid drinks. After sifting through the many mac-and-cheese dishes on its menu, the Heat Seekers hosts chose the spicy Habanero. A glass of milk is right under it on the menu, so you have relief close at hand.

The Alligator Cafe promises an authentic Cajun menu. But as Heat Seekers Aaron Sanchez and Roger Mooking learned, they also turn up the heat with their Wicked Crawfish Enchiladas.
