It would cost about USD 5.0 here because of the fact that the inflation is 25 percent up (food commodities)...
It varies for me; however, I love Panera Bread. That usually costs about $7.35 (half of chicken caesar sandwich and bowl of broccoli and cheese soup) I love it.
My lunch cost me just 1$ but sometimes I do not eat to save 1$ , yes just 1$ because we are not from the US or european countries
Food in Serbia (where i was born) is extremely expensive. I dont like eating out, and i don't count how much my home cooked food costs.
Sounds delicious haha wish we had a rubios here in Australia! Mine was free today (technically nothing is free) but i made lunch and took it
