Isn't there a place called piggies or something like that? I really like Betheny Blues but that's in Rehoboth. Honestly I've never been but the sold food at Punkin Cunkin and so I'm really looking forward to going there soon.
Where Pigs Fly like Deb said is a good place, there always one Star Steakhouse & Saloon eventhough its overrated sometimes. Theres a BBQ Grills INC i heard was pretty good.
If you're in northern DE I would stop by Durham BBQ. A really small place off of Elkton Rd. near the MD border (so small that you can only eat at the tables outside), but better than any other BBQ place I've been to in DE (I grew up in DE). If you stop by during the cold months you're pretty much forced to get it to go, but across the street is State Line Liquors, which has a HUGE selection of craft (Rogue, Stone, Dogfish) and Belgian beers.
