Salt Lake City eats?
That thread is pretty old now I think. Right now downtown my favourite restaurants that fit your budget would be Takashi (unbeatable sushi), Eva (pocket friendly small plates and drinks) and the Tin Angel Cafe (new American with a focus on local produce)
Also consider Cucina Toscana (fabulous Italian), Martine (excellent tapa), and Bambara (upscale New American). All are within walking distance of the downtown hotels and have very good food. Excepting alcohol, you should easily meet your $50 budget at each of those establishments.
