The service needs improvements!
We went there for a late night meal, the food was not bad. After waiting approximately 30 mins for our food to arrive, the waiter ended up saying that the kitchen made a mistake with our orders which is the reason for the delay. When the food finally arrived, the sever forgot to give us utensils and also never checked up on us. In the end, we had to wait another 20 mins for the bill.
The only pro is the fact that Denny's are opened 24 hours.
