Maximum Limit For Sodexo

Dear Seniors,
Please guide if there is any maximum limit for the sodexo coupons issued by company. Is it only Rs.1250/- per month considering Rs.50/- per mean during office hours?

Not much experienced into this but whilst even i was searching for this information long back I got to know this -
Food allowance is taxable above 50/- a meal per day.
Also note if someone works double shift, accordingly it would be calculated.
However when sodexo coupons or such vouchers are given, they are tax free.
Whilst I was intern with one of the reputed company, we used to get -
400 Rs. Canteen coupon / voucher per month
400 Rs. Sodexo coupon per month.
