Unfortunately, Beantown is not known for fiery cuisine. Were a pot roast, meatloaf, and mac' n' cheese city. I had enough of that stuff growing up to last a lifetime. Your best bet for spicy food is Asian (Indian, Thai, Vietnamese). Since I don't know the exact names of restaurants, I'll give you the neighborhoods to check out. Central Square, Cambridge-LOTS of ethnic places within 2 blocks (Indian x 6, Chinese, Mexican-"Picante", Ethiopian, Jamaican). Inman Sq, Cambridge-(Portugese, Brazilian, El Salvadorean, eclectic Pacific Rim "Jae's"). Brighton/Allston-(S. Indian, Thai, Vietnamese, Chinese, Brazilian, BBQ, taqueria). Waltham/Moody St.-there's a bunch of Indian and Thai places here along with BBQ, Tex-Mex, & Italian-check out the little Spanish market here (Bufalo chipotle & El Yucateco dirt cheap). East Coast Grill in Inman Sq. Cambridge, Green St. Grill off Central Sq., and the Blue Room in Kendall Sq. might heat things up for you. Good luck Jeffro
