ジョナサン 水道橋店

The food is ok. Loved the free flow of bar drinks. The waiter was helpful. The only thing is when I went to pay my bill, before the cashier handed me the change, he looked as if he was asking something from me with one hand holding the change & another hand wide open. The communication was hard though since he can't understand English. In the end, he just gave me the change. Was he asking for a tip? To my understanding, Tokyo restaurants don't have tips.
