After 10days trial, finally I go with 20days service.
Considering about the price, I think this meal is value-for-money good choice. I used different service provider before, but I feel this one is better in quality even though food portion is ... Moreslightly smaller than previous one. Food is generally ok, but there is some variety in taste, some is nice, some is so-so ok. And sometimes I found space filler menu... only a few piece fish ball in one big container. Overall, I think I made fair choice, and satisfied the service for what I paid.
