A few I found interesting:
Orchia, proposed by the tribune C. Orchius in the third year after the censorship of Cato B.C. 181, limited the number of guests to be present at entertainments
Aemilia, did not limit the expenses of entertainments, but the kind and quantity of food that was to be used
senatusconsultum was passed ... for the purpose of restraining luxury, which forbade gold vases to be employed, except for sacred purposes, and which also prohibited the use of silk garments to men
