    The food was good. The server had too many tables and we rarely saw her. My son’s order was incorrect and I had to ask for my salad to go because it was never brought out. We asked the bus boy to get our check because we had been sitting there waiting for 15 min. Another table had their check, but took them that long for the server to come back for it.

    Luncheon birthday celebration for friend. Ordered from luncheon menu. Excellent choices and combos only $14.99. Large portions. Wonderful service and a comp BD dessert to feed a family of 4. Was a Monday and the restaurant/bar area very quiet. Would patronize again.

    Food, service, and atmosphere were good… Not sure why but website shows happy hour until 630 but menus at restaurant show 6. They honored the 630 but had to complain which I hate doing… after all it was the reason we went there!

    Not what it used to be. Server was unprofessional- Curt, forgetful, not attentive. This used to be a very busy Saturday night spot but now it is mostly empty. Not sure why. All in all experience was just meh. Not in a hurry to return

    The service was outstanding and the food was delicious. It was my first time there. We had 7 people and sometimes that creates an issue with getting everyone served timely. It was not an issue. We were all served at one time and everyone’s order was perfect. We will definitely go back soon.

    This was our first time ever eating at Walnut Grill as we had just moved over in this area about 4-months ago. For our 32nd wedding anniversary and we couldn’t have picked a better restaurant to celebrate at. Everything was perfect- the food, drinks and our waitress.

    The floors were do dirty and sticky that we could feel and hear our shoes ripping off the stick as we walked. Our table was not clean or set for us despite our reservation (wet cup rings from prior party and no flatware or napkins). The windows on the doors dividing the dining rooms were so thick with fingerprints that it was impossible to see through them. Many menu items listed on the website were not presented on the buffet, such as the eggs benedict, fresh omlettes, carrots, muffins/danishes, cod. Much of the food was not well prepared. The pasta was dry and overcooked. The chicken was mushy and underwhelming. The salads were drenched in salad dressing. The scrambled eggs were over cooked. The cheesecake was warm and melting and the only other dessert was perhaps German chocolate cake, but it was impossible to determine what it was. Our server was certainly nice enough, but she never took any of our dirty plates away and we were never given the option for clean flatware. I definitely expect a cleaner restaurant, better quality food, and much better service for a $25 lunch buffet. I will not go back.

    Angelina was great. She was attentive, shared with us one of the dishes we ordered she recommended because she had it last week. Another member of the team was equally engaging. Prices were very reasonable. Everyone loved their food.

    We got there and were surprised that they only had a Mother’s Day brunch for $39.99 per person! There was nothing about it on their website or on One Table!
