You can request non spicy, no seafood etc and on days when you dont feel like eating tingkat you can call a day earlier to inform them you wanna rest for a day. Pretty flexible. As for price wise, its $130/person for 20 days for 3 dishes 1 soup/other. To add rice must pay another $10 so i cooked my own rice. No delivery on Sat and sunday.
Most importantly no msg.
Hope this info helps. You can refer to their website for more info.
