Hi! I work in a hotel, and do promotions for the hotel and the restaurant, and here is my opinion.
First, the name of the restaurant - Chang it. You don't want people thinking it is a DUMP, and that is what they subconsciously think when they hear the name.
Also, brighten up the colors - brown is mundane. Use bright colors, red, orange, yellow...
Give it a new, fun name. The do a Grand Re-opening. Put up flyers, let the local newspapers know, if you can afford it, put an ad in, but if not, then invite the food critics in to eat.
Make certain you have enough staff, and that they are giving good customer service. Make certain the food is really good. Invite family and friends for a pre-opening night, and let them give you their honest feedback, then take any action as appropriate to make necessary improvements.
Once you have the product and service right, you need to promote it. Go to businesses close by and offer a discount for their employees. Go to apartment buildings/condos/homes nearby and leave flyers. Put up info at the library, or any other place you can.
Good luck!!!!! I know you can do it!!
