★ 5★ 4★ 3★ 2★ 1Dining at Trattoria Diane is a really nice experience. The staff are all friendly and attentive and provide perfect service. The menu is varied and with lots of good choices. We had the duck and halibut with salad and burrata appetizers and two of their dessert selections. Everything was delicious. The prices are a little higher than expected with glasses of wine costing $15 and $18 but wine prices have increased recently so the restaurant is simply passing the added cost to their customers. Overall at this restaurant you get a better experience so the cost of the meal is worth it.
September 07 · Robert RothschildAs always, this restaurant is amazing! We started with tuna tartare which was great, and very fresh. I had the steak that was cooked perfectly and my wife had the ravioli. For dessert we got angel food cake and apple pie, both of which were delicious. Highly recommend this restaurant
June 14 · Ryan OlsheverWe have been going to Diane’s for ages and we really enjoy the restaurant. Historically, the restaurant offered a pretty good value for the quality. On our most recent visit, however, we noticed sharp price increases on the menu long after inflation has stabilized, so we will be looking for more reasonable dining options going forward.
March 09 · Cassi VossYes, it’s been around for years but it’s excellent. Service was attentive, portions were good, food was tasty and well prepared. And the desserts are fabulous.
December 16 · bill dSuch a quaint cozy restaurant! Service was so accommodating, kind and patient! Food was delicious! My mom and I booked my bridal shower at Diane’s, but we wanted to come for dinner and try the food! And it was so so good! We ordered the filet of sole Milanese and the carbonara! 10/10!
