For the mentor lunches you have a choice of chicken or vegetarian lunches for both Friday and Saturday, however if you use Autofill to fill out your contact info, it will automatically fill all 4 lunch options. So just double check your lunch preferences before you submit so you don't accidentally buy 4 lunches like I just did
I was so excited and in a rush I didn't think to double check the info. Luckily I called and had it fixed within minutes, Taxi rules
