About this restaurant

  • Good for special occasions
  • Charming
  • Good for groups
Please call the restaurant at 203-754-5111 for additional availability.

The legendary history of Diorio Restaurant began in the 1920s. The late Rocco Diorio was responsible for the fine traditional food and many lasting memories for most of the people in the greater Waterbury area. The restaurant was closed in 1980 and reopened in 1991 after total restoration to its original splendor. The legend continues as we remain true to those endearing memories.

We have the original marble bar, over-sized mahogany bankers booths, tin ceiling, and the most impressive acid-etched mirrors displaying historical Waterbury. Diorio Restaurant has once again reclaimed its reputation as Waterbury's finest.

    This was my first visit back since Covid and the closing for renovations. I must say my experience was STELLAR. On a scale of 1 to 5 stars, Diorio's is TEN STARS. Among us we shared the ceasar salad, the freshest calamari on earth, and the OMG beef carpachio. We also shared the world famouse Chicken Parm w/their award winning bolognese and the Cod Special which was as thick and fresh as if it came off the boat that morning. Our server was James (JT) and knowing that we were celebrating a birthday, made things extra special ... or did he ... we walked away debating that because we were quite sure JT is always on top of his game. JT is straight out of Beauty and the Beast ... you know ... the dinner scene ... Be Our Guest. Although we failed to ask, we agreed that JT surely had training at the Lucerne. Bravo and Merci, JT. Of course the dessert selection was the toughest part of the evening. How does one possibly choose from the 6 or 7 gourmet delectables. We thought that adding a gold birthday candle may have been dangerous since we were already so full that it might have resulted in an explosion. Timing of each course was perfect. JT paid close attention to our progress and fired up the next course with precision timing. Although this was not a landmark birthday, a young 61, JT certainly turned it into a most memorable celebration. Starting with JT and all the way around the restaurant, THANK YOU SO VERY MUCH to everyone for the TEN STAR experience we thoroughly enjoyed on the evening of March 20, 2025.

    Service was great. Food was not. Sea bass special was a small portion, veal was clearly pre-cooked with some cheese slapped on top. Cold in center.

    Diorio’s is truly a gem in Waterbury, everything from start to finish was fantastic. The moment you walk in, you’re greeted with a warm, inviting atmosphere that perfectly blends classic elegance with a welcoming neighborhood feel. The food is exceptional. Every dish (sword, veal, chicken parm) was prepared with the highest quality ingredients, cooked to perfection, and beautifully presented. The service is top-notch—attentive, knowledgeable, and genuinely friendly. The staff (JT was our guy) goes above and beyond to make everything great, offering great recommendations and ensuring a fun experience. I’s easy to see why it has such a devoted following. If you’re looking for an elevated yet welcoming dining experience with outstanding food and impeccable service, this is the place to go. Highly recommend!
