If you carry a
GSM phone (particulary and 850mhz and 1900mhz phone), do a
network search. If nothing comes up in an urban area and you are not
underground, it is a good bet that a jammer is in place. Also stand right
outside the door of the restuaraunt and you can figure this out as well.
With hotels, what you need to figure out is what technique is being used to
jam the phone. A little led in the glass and carefully chosen insulation
can be a legal passive jammer.
