Eating at cafes is complete nonsense. This little house is simply located in an area that's like a suburban district, but within the city limits, and not too far from the center. However, it's still about 20-30 minutes by taxi to get to a decent place, and the same amount of time to get back (including delivery and all the fees) + it takes at least 2-3 hours to prepare everything. In the end, three meals will take up 6-8 hours of time, not to mention the cost. As an alternative, there are many delivery services for pizza or sushi; if you search online, you can find some that deliver decent food.
The main problem is that one person doesn't eat, while another doesn't drink. 19 will be fine, but 1 will complain later.
