The proprietors of Bangkok Thai restaurant in Dover have opened their new Mariners Plaza/Lewes location in the space formerly occupied by Sushi Heaven. Seems to be a nice addition to the Lewes lineup. I've been there a few times and still hope that the dishes will be more creatively spiced. Take a look at the gallery for a sneak peek at the dishes.
Feedback to this point is starting to get better, so it looks like they are getting it together. See their hours of operation at cheap eats/specials.
Take a look at the Dover menu here. That and the Rehoboth version are very similar.
