Yes.
Similar to burnt candy or something sweet that has been burned. It is a very unique smell that can't really be described.
To test for a blocked vent, plug the sink or tub. Put at least 2 inches of water over the plug. If the smell ceases, you have a blocked vent. The smell is caused by methane gas, which can cause many health issues.
