Invited client over for lunch but the service was awful. First it took forever to order. Then it took a long time for the water to get refilled. Our waitress never showed up during the meal to check in on us and we had to wait quite some time for the check and then for her to come back to take the card. The client had to leave for the next meeting while we waited to pay. No complaints about the food.

Great spot for the Buffalo Bills games. Terrible service! Every time I looked over to order food or drinks, our server was sitting down on her phone. Super frustrating, took us almost 30 minutes to place a food order from the time we sat down.

Had the pleasure of visiting Friday evening. Made a reservation ahead, and were greeted as soon as we walked in and sat at our table, 5 minutes before reservation. Enjoyed the egg roll appetizer, proper burger ♨️ and a few beverages. All of which were outstanding! The service was extremely friendly and efficient. Thank you Proper 21 we look forward to making this a routine stop when in D.C.
