One of the cardinal rules of a party is "Always have more than enough food for everyone," a rule superseded only by "Never mix alcohol with access to a particle accelerator." Secure sustenance for all revelers with today’s Groupon: for $25, you get $55 worth of catered deli fare from Saul’s Restaurant & Delicatessen in Berkeley.

Saul's was highlighted by the New York Times for its organic, often locally sourced, deli-style comestibles catered for breakfast, lunch, and dinner. Mumbling morning bellies make peace with platters of smoked salmon accompanied by bagels and cream cheese ($75 for 10 people), washed down with freshly squeezed orange juice ($2.50/person). Disseminate hors d'oeuvres such as the hummus platter, which comes with pitas, olives, and feta ($12–$35), or deal in knishes ($2.50/person) and latkes ($2.25/person). Customizable meat platters can feed between 5 and 20 hungry humans or two famished bicycles with a selection of turkey, pastrami, roast beef, or corned beef ($40–$135). Five varieties of fresh bread and a posse of condiments and sandwich vegetables chaperon the savory slices. Wet whistles and other woodwind instruments with bottles of cane-sugar sodas ($3 each), and sate sweet teeth with cookie platters ($3/person) or a whole cheesecake to toss at insubordinate bassoonists ($38).
