As part of my business plan package, I got access to the breakfast buffet each morning, which was fantastic. The food was great and hearty (some days, I didn't even need to eat lunch - mostly, I only needed a light lunch) enough to fuel a day of exploring the city. The staff is friendly, but some of the waiters/waitresses seem to get a little suspicious of stealing, especially concerning the buffet. Even though I paid and was doing some work, I got the third degree when grabbing a scone after my plates were cleared. Overall, I thought this breakfast helped make my stay at the Hyatt Regency San Francisco all the more enjoyable.
