How you meter it will depend on what you want your interpretation of the image to look like in the end and the scene. If it's low-key lighting at night and you want to print with texture in the whites still, expose off the brightest spot and increase the exposure 2 stops -you probably don't want to meter off a light source, but something that you want to be bright white, but still with texture. Bracket above and below the exposure (1-2 stops) when you find a composition you're intrigued with. One of the 3 will come out printable. You just need to make sure the film is developed properly and that should work for you. If it's a scene with a balance of lights, a spot meter of 5-15 degrees that reads 18% grey on the scene should give you a decent approximation of where to start bracketing.
