• I am not very happy with my time arithmetic. I'm sure there should be more convenient and straightforward way to do this without using all those coercions and transformations between time's data.

• It would be nice to add custom errors with more descriptive messages (e.g. instead of should match restaurant schedule it might be something like: does not match restaurant schedule, a reservation may be made on or after 11:30.)

• For a real-world application there also a need to manage time zone issues.

• At the moment, if a reservation overlaps with another reservation for the same table it will be restricted (cannot be created) - it might be better to move the reservation to the nearest free time (e.g. table is reserved for 12:00-13:00 by a user A and a user B wants the very same table to be reserved for 12:30-14:00, so, we can move their reservation to 13:00-14:00 instead of restrict it completely). The same is for restaurant's schedule - fit into schedule instead of decline.
