I need to serve like 50 or more empanadas at my party this weekend. I would make them, but I won't have enough time. I'm trying to find a reasonably priced place that could cater them. My first choice would be Orinoco, but they're $2.50 each - no pro rates for larger quantities. I might end up going getting them from La Mamma in Allston, but they don't give me large quantity pro rate, they're still $1.50 each. Any suggestions?
