I have attended quite a few casual events that have been catered by Blue Ribbon. These events were hosted in backyards, etc. to celebrate First Communion, high school graduation, etc. Food was well packed, abundant, and darn tasty. In fact, they would be on my list of caterers should I ever be celebrating with friends/family.
Blue Ribbon catered a casual dinner for 35-40 people for us at our home in June - the service was great. Prompt, attentive, and totally flexible (we were going to do outdoors, but because it rained for the entire month of June, we had to squeeze into a smaller space).
Food was excellent - completely on par with what you'd get at the restaurant. We didn't have any fish - the meats were the best, though.
Let me know if you have any specific questions. Can't say enough good things about the catering.
Oh - and yes, we had TONS of extra food. We ordered for the right number of people but then had enough to send three meals' worth home with the babysitter, brought dinner to my sister's the next day, then brought more to my dad's... and still were eating BBQ for a week.
