  • Things are running very well. The sub freezing lobby of the new building was pulling heat out of the old building since your guys were there, no issues. As always, you guys are the standard for pros to follow. I appreciate your help.
  • Please share my sincere thanks with the guys who traveled to Cravath today through what I am sure were difficult road conditions. Day & Nite/ All Service is an enormous part of FLIK's and Cravath food service success. Thank you for all you do!
  • Thank you. The machine is working properly. Glasses look great and soap usage is down.
    Nice work.
  • Thank-you Rick! Had a lot of fun cooking with the new stove today. Steve and Paul were awesome to work with!

  • Dear Rick and All Service Staff, I just wanted to thank your staff for the great job they did installing my Electrolux ovens. It was not an easy task with the many hurdles they had to deal with but they completed the job and were professionals in the process. The team yesterday deserves a lot of credit for working together to get the job done. It was a pleasure to watch them work.
