Bayou Bakery in Arlington.

I'm hosting an evening birthday party where we'll serve apps/snacks and drinks. I was thinking of apps like pimento cheese, deviled eggs, chips/crudites and dips, etc. -- slightly upscale pub snacks. Mostly cold/room temp foods. Any recommendations for a place? Party will be in DC, but we could pick up from surrounding areas within a reasonable distance. Thanks in advance!
