I love cafe azafran (I think it's cafeazafran.com - or do a webs earch) in Lewes; also, I made a post further down on the page about Kindle, the new restaurant at Paynter's Mill, it was excellent. (kindlerestaurant.com).
I think all the rehoboth ones (blue moon, espuma, cloud 9, etc.) are well reviewed on here by people more qualified than me. I have so many old favorites in town, and so rarely get home, I don't go to the biggie popular ones (Dos Locos, Iguana Grill, Adriatico and I love Planet X and I rarely see it mentioned here). Chez la Mere was recently purchased by the Espuma people and is very good as well now.
