you should go to Kalachandjis' a vegetarian restaurant in east dallas...it is in a beautiful hari krishna temple. the restaurant part is in an open air area with beautiful trees. food is great. you can check out the temple while there...very cool.
or mama fey's bbq in deep ellum. last time i was there i sat at the bar and watched an old episode of bonanza on a little tv while i ate their excellent brisquet. and you get a free can of budweiser with your lunch.
