Been here twice since phase 4 of Covid Any apprehensions I may have had in regards to dining out were immediately squashed. We have sat outside as well as inside and everyone is doing a phenomenal job keeping us safe. From spaced out tables to sanitizing stations and more. Highly recommend! Oh and definitely order the poke nachos! It’s one of the things that brought me back. Delicious!!!

We had an excellent meal and an awesome server. They even gave us a lovely outdoor table away from other patrons that was romantic and a bit private. We’ll definitely be back.

Our experience was horrible the waitress took our appetizers and didn’t come back for our dinner order for almost an hour, we order dessert for our coffee and check and no dessert and the waitress never came back. What a disappointment spending almost $350 on dinner and it was a complete disappointment the service was horrible. She also spilt our drinks thru the table we ordered two martinis and we were on the outside table and went in my husbands and nine feet and my husbands shorts. This was a horrible experience and not worth the money. As well as the swordfish was so over cooked and dry.

Sat at the outdoor patio, party of 4. Felt very safe with all the precautions the restaurant had in place with covid. The watermelon feta salad was excellent and the sushi is always so fresh. We got 1 of each dessert, I don’t even like chocolate cake and it was amazing. The manager Ron is so nice. Great place to go for casual dining or Date night!

As always, a wonderful dining experience. I had the black bass special which was done perfectly. It goes without saying that the flavor and presentation are perfect. The only disappointment was no popovers being made presently. But, I did get a special birthday dessert and gift.

We did not know what to expect with all the restrictions, but were pleasantly surprised, we sat at the bar, enjoyed Happy Hour drinks, ordered our food, which was perfect, nobody rushed us and we thoroughly enjoyed our visit, Hope to return soon! Already recommended Happy Hour to my granddaughter and her husband who live near by, they are excited to try it.

Service among the worst and cost among the highest. Drinks full of ice, including “pitchers” that were actually mason jars.

I asked for the sirloin wellington meal with additional mashed potatoes on the side-got the sirloin and mashed only-none of the entries that came with the meal.

I support local businesses but not this one again. Did I complain? No, because the staff was not trustworthy.

P.S. the sushi was good,
