License requirements for cloud kitchen in Mumbai

Hello, A friend of mine is planning to start a Cloud Kitchen in Mumbai. He is getting very conflicting suggestions regarding the license requirements required. Is a health license from BMC required for a cloud kitchen? (The cost of acquiring this license is about 5Lakhs from what he's been told). The GST, FSSAI, Shop and Establishment License seem to be pretty straightforward to acquire. The tricky ones where physical inspections are involved (hence, bribes) are the Fire license and Health License from the BMC. The Fire License seems to be costing a bit upwards of a lakh. However, the Health License seems to be something that costs 5 Lakhs+. Do cloud kitchens need the health license from the BMC? A licensing consultant mentioned that it is required only for dine-in restaurants and not for Cloud Kitchens, but another said it is required even for cloud kitchens due to a recent change in law. Would love to get some insight on this from someone well versed on the subject. Any informed advice/suggestions would be extremely helpful.
