Most have heard about the Lake Agnes tea house, but not everyone knows there is another one at the Plain of Six Glaciers. At 5.5 km one way, it is a longer trail that the one to Lake Agnes tea house, but it has less elevation and is typically quieter and feels more remote.
Make sure to continue to the viewpoint at the end of Plain of Six Glaciers trail which is a bit over 1 km from the teahouse.
