I am in search of an affordable caterer in the Oakland area who can provide us with appetizers for our baseball "tailgate" themed wedding cocktail hour. We're thinking things like pigs in a blanket, sliders, garlic fries, nachos, chili, etc. We'll be having approximately 150 guests. There will be a full dinner afterward (we already have a BBQ caterer lined up), so we only need the cocktail hour catered. We don't care about having passed appetizers - cost is more important to us than presentation. Any suggestions?
