I'm in Biloxi on business this week, and ate at Jia last night. I had a reservation for 5:45 PM and arrived about five minutes early. I was seated immediately, and given the wine list, daily menu, and sushi menu.
I selected the "Bubble Gum" roll (Tempura Shrimp, Cream Cheese, Poached Shrimp & Eel Sauce) from the sushi menu, and the orange chicken from the daily menu. My server offered to bring the sushi as an appetizer, and I gratefully agreed. The roll was brought out in six or seven minutes, to my pleasant surprise.
Just as I was finishing my sushi, the orange chicken was brought out, and served at the perfect temperature.
I enjoyed my orange chicken (with steamed white rice) but had to decline dessert, as the portion was quite large.
Overall, I enjoyed the food, but found it slightly overpriced. The service, however, was absolutely excellent--quick and attentive.
I found the restaurant to be very quiet, which might make it a good match for a business dinner, however, this might be because I was dining so early.
Overall, I found "Jia" to be an above-average choice, and because of its convenient location (if one is staying at Beau Rivage), I could see myself eating here again on a future trip.
