Our Story: It Began with One Man, One Toolbag, and a No-Shortcuts Attitude
Before websites were a thing, there was Mike Rayburg—a technician known for fixing problems, showing up on time, doing things right the first time, and treating every kitchen like his own. He built a strong reputation among chefs, school facilities, and restaurant owners throughout Pennsylvania.
After more than 30 years inside the hottest, busiest kitchens you can imagine, Mike founded Rayburg Appliance Service (RAS) in 2003. Today, RAS doesn’t just serve kitchens—we help keep them running around the clock. And now, we’ve taken that mission a step further with the creation of PartsBistro.
Our Businesses: Parts Bistro (PB) & Rayburg Appliance Services (RAS)
PartsBistro started as an extension of Rayburg Appliance Services. Together, they serve the same mission from different angles: to keep commercial kitchens running smoothly, safely, and with minimal downtime.
Rayburg Appliance Services handles the installation, repair, and maintenance of commercial kitchen facilities across the United States. PartsBistro complements this by offering a wide selection of high-quality replacement parts for commercial kitchen equipment.
Our Promise: Replacement Parts You Can Trust, Support Team You Can Count On
After decades in the field, we saw the problem: finding quality parts was harder and more expensive than it should be. So we built PartsBistro, a technician-backed hub that makes it easy to get the parts you need at the best price. We offer both OEM & aftermarket parts for the brands we’ve trusted for years. Whether you're replacing a single component or ordering in bulk, we’ve got you covered. With local delivery in Pittsburgh and Greensburg, and nationwide shipping, we make sourcing simple and reliable.

Our Team: Experts in Every Corner of the Kitchen
What began with one man, one toolbag, and a no-shortcuts attitude has grown into a trusted team of certified technicians who know their craft. Today, we bring over 30 years of real-world experience to every kitchen we serve.
We’ve diagnosed failing compressors at 5 AM, tuned steamers on the fly during the school lunch rush, and helped chefs stay open during surprise inspections. From hot-side to cold-side—ovens, fryers, steamers, walk-ins, ice machines, and more—our team has seen it all and fixed it all. Every part we stock is one we’ve personally installed or replaced. We know what fails, what holds up, and what gets your kitchen back up and running—the right way, the first time.
