Hello Rashesh,

Yes there are some Indian restaurants in D7 around Skygarden.
Ganesh Indian Restaurant is one of them.
Add: So pmh, 54 Đường số 6, Tân Phong, Quận 7, Hồ Chí Minh, Vietnam
I sometimes go to their D1 branch. Good food at reasonable price. They serve veg thali and whole lot of other veg curries etc. Google their site and menu.

If you are coming from India, you may consider bringing an Electric Roti Maker to make your own fresh Roties. One plain small round chapati costs around $2 in most Indian restaurants.
You can use it in your hotel room, no problem.  At the time of leaving HCMC, if you wish, I can buy it from you. In fact I am looking for one at the moment. Haven't found it so far. https://www.expat.com

Talk to the hotel beforehand if they can help warm your food in their kitchen micro oven.  They will do it, no problem.

Vietnamese veg food is also tasty. Give it a try. Look for the word ''An Chay'' .. these are veg restaurants.

Remember this handy phrase:
Tôi ăn chay == I am vegetarian

D7 is a nice and well spread out district. Many Indians are there in the PMH area.
