Hi Aadil,
Your team come to discuss with me about lunch and dinner for participants. May I give a suggestion as below
1. For lunch, dtac Academy could help to prepare halal food set for participants rather having a lunch outside
2. For dinner, we do recommend you to organize a group dinner to all participants only on Day 2 (Thai Restaurant on Sathorn road like Baan Khanittha or Secret Garden is also easy to access)
If above recommendation sound great for you, please feel free to let us know
