I'm going to be spending a few days in SD next week, probably near the Hillcrest area. I'll have a car, and am willing to drive at least 20-30 miles for great food. Even 40 miles if it's really fantastic. I'm seeking recommendations for some of the best spicy food in the area. I'm not just looking for intense heat (though heat is great), but also complex, layered flavors. Favorite cuisines include Indian, Thai, and of course Mexican, but recommendations needn't be limited to that. The last couple SD Mexican restaurants I tried were mediocre and touristy. I did hit some fantastic Indian restaurants sort of northeast of the city (near a military base, I think).
So, best recommendations for spicy, intensely flavored foods? Thanks!
