Best Spots for a Birthday in Mumbai/Thane

Hey everyone! My best friend’s birthday is coming up, and I need help planning a full day out in Mumbai/Thane. We’re a group of four and want a cozy, fun, and memorable experience. Looking for recommendations on restaurants, rooftop spots, cafes, or any place with great ambiance and views but no adventure activities pls. I’d love suggestions to plan the entire day, from breakfast to dinner, including good places to visit, chill spots, or any unique experiences to make it special for her. Budget is flexible.
