Restaurants after 1 year of lessons? I would have been terrified and mortified if my teacher would have send me to those! It would probably have stopped me from liking to dance at all. Restaurants are for the more experienced dancers as its not just dance skills and performance skills but also dealing with nasty clients and nasty restaurant owners. Not something you'd want to start with! I think if teachers want to introduce students to performing solo, start with halfla's and then friendly private gigs and maybe small festivals. And probably with other dancers doing solos too so the students doesn't feel so pressured.
