Dia de Posole

This is a little embarrassing.I have been coming to Ixtapa for at least 35 years.I have had posole many times.Tamales Any, lots of places on Posole alley,Salsa Brava.I have unfortunably ,never been to a real authentic Posoleria.This year my daughter and son in law are coming down for 2 weeks and I would love to let them( and me) enjoy the real thing.However I am a bit nervous.What do we wear?Beach stuff,dress up stuff,shorts,long pants ,tee shirts,collar shirts,real shoes,sandals?It will probably be Santa Prisca as it easy on the bus from the Marina in Ixtapa.What time should we go?What should we drink,tequila,mezcal,beer,horchata,jamaica? What kind of posole,verde,blanco,rojo?Is anything, else served ,tacos,enchiladas,tamales?Is there music? Is there dancing?Are there many grigos?Va a sera comodo para mi familla? Gracias
