I decided to put water all around it, because I wanted to be the cafe that people focus on. But, should I delete the water and add activities that people could do? (Outdoor.)
I would go for your cafe on an island, it will make the cafe look better and also more realistic.
Since you are a clothing designer, you could also add a building with your own Cookie Cafe Merchandise.
If you looked at other cafes, this is far from those and does not even look like a cafe. I’d advice to make a lobby first which leads to the cafe. Cafe having it’s windows, a nice welcoming door and etc. Also having a sort of beach type theme around the map could give it a little bit glow.
