2 looking for a decoration company that can decorate in Thai style only needs Thai style and does not need to use many good materials. The same is true for preparing tableware.
3 personally go to Thailand to taste all kinds of dishes, especially special dishes. This is the restaurant menu you want to make and the guarantee of your future customers. Find a chef. It's more fun here. It's super expensive to invite a chef to cook Thai food in China, but it's cheaper to go to Thailand and invite a chef to cook in China. It depends on your own luck and whether you can find a cheap good chef.
4 please kitchen handyman and restaurant waiter, welcome guests, food delivery staff, cleaners and so on.
5 after the renovation, the chef and waiter are in place and put into trial operation.
you can refer to banana leaf restaurant. Thai food for ordinary consumption.
