Not required, But for food handling purposes, it's probably not advised to wear acrylic nails as they can possibly, break and fall into customer's food.
There are periods that need to be covered (i.e. 10-2 or 5-8) being part time. Most hours are set in stone, weither you are working mornings, afternoons, or both.
If I'm understanding the question correctly, Mucho Burrito has an obvious Mexican vibe, since they are labelled as an authentic Mexican restaurant. The environment is pretty good, once everyone is trained and knows what they are doing then the lunch and dinner rushes are smooth, productive and fun!

Where do you work before Muchho burrito?
Do you have any experience of working in restaurant?
