mess hall / canteen
A dining hall for a specific group of people, especially for officers in a barracks or for employees in a larger company or public authority.
Die Offiziere trafen sich zum Mittagessen im Kasino.
The officers met for lunch in the mess hall.
The two meanings can be distinguished well by context. If it is about gambling, money, and entertainment, it refers to a gambling casino. If it is about meals in a barracks or a large company, it refers to the dining hall.
Am Abend versuchen wir unser Glück im Kasino.
In the evening, we’ll try our luck at the casino.
Pay attention to the difference between 'ins Kasino' (into the casino, accusative), which describes movement, and 'im Kasino' (in the casino, dative), which describes a location or stay.
Wir fahren heute Abend ins Kasino.
We’re going to the casino tonight.
This meaning of 'Kasino' (mess hall / canteen) as a dining hall is limited to certain groups. You typically find it in the military ('Offizierskasino', officers’ mess) or in large companies and public authorities for employees.
Das Essen im Kasino der Firma ist heute besonders gut.
The food in the company canteen is especially good today.
canteen / cafeteria
Kantine and Kasino can both refer to dining rooms within an institution. A Kantine is generally intended for employees or members, while a Kasino specifically refers to a dining hall for a particular, often more exclusive group. In a barracks, “Kasino” is therefore especially suitable for the officers’ dining room.

Die Offiziere nehmen ihr Mittagessen im Kasino der Kaserne ein.
The officers have lunch in the officers’ mess hall at the barracks.
Die Soldaten holen sich ihr Mittagessen in der Kantine der Kaserne.
The soldiers get their lunch in the barracks cafeteria.
